All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Detailed descriptiona method for improving transmission spurious according to an embodiment of the present invention is applied to a mobile terminal, where the mobile terminal may include a transmitter, a power amplifier, a first variable notch module and a second variable notch module, the first variable notch module is connected to an output terminal of the transmitter and an input terminal of the power amplifier, respectively, and the second variable notch module is connected to an output terminal of the power amplifier.
Referring to fig. 1, a flow chart of steps of a method for improving transmission spurs in one embodiment of the present invention is shown.
Optionally, step 110 may obtain the first transmission spurious spectrum through data returned by a test instrument for testing the spurious emissions of the mobile terminal, and determine that the mobile terminal has the transmission spurious when the spurious emission power corresponding to a frequency point in the first transmission spurious spectrum where the spurious emission power is the largest is greater than a preset power (for example, a power in a spurious emission requirement of the national radio commission or a power predefined by a manufacturer). Wherein the factory-predefined power requirement is less than the power in the national radio commission's stray transmission requirements. Specifically, the transmission spurious spectrum includes information such as spurious transmission power corresponding to the frequency point and the frequency point.
Specifically, step 110 may adjust the operating state of the transmitter by adjusting an operating parameter of the transmitter, and step 110 may adjust the operating state of the power amplifier by adjusting an operating parameter of the power amplifier. The working parameters of the transmitter can be the working parameters of the transmitter such as gain, supply voltage, bias current and the like; the operating parameters of the power amplifier may be gain, supply voltage, bias current, and the like of the power amplifier.
Optionally, after the operation state of the transmitter is adjusted in step 110, the transmission spur spectrum of the mobile terminal is the first optimal transmission spur spectrum. That is, in the process of adjusting the operating state of the transmitter, the spurious emission power of the frequency point with the maximum spurious emission power in the first optimal spurious emission spectrum reaches the minimum, and even if the operating state of the transmitter is continuously adjusted, the spurious emission power of the frequency point with the maximum spurious emission power cannot be smaller. Optionally, step 110 may obtain the first optimal transmission spurious spectrum by data returned by a test instrument testing the mobile terminal spurious emissions.
Optionally, after the operation state of the power amplifier is adjusted in step 110, the transmission spur spectrum of the mobile terminal is the second optimal transmission spur spectrum. That is, in the process of adjusting the operating state of the power amplifier, the spurious emission power of the frequency point with the maximum spurious emission power in the second optimal spurious emission spectrum reaches the minimum, and even if the operating state of the power amplifier is continuously adjusted, the spurious emission power of the frequency point with the maximum spurious emission power cannot be smaller. Optionally, step 110 may obtain a second optimal transmission spurious spectrum from data returned by a test instrument testing for mobile terminal spurious emissions.
Improving the transmission spurs of the mobile terminal can be achieved by step 110.
And step 120, if the transmission stray does not meet the preset condition, adjusting the notch frequency point of the first variable notch module and/or the second variable notch module.
In particular, the preset condition may be a national radio commission spurious emission requirement or other spurious emission requirement predefined by the manufacturer. Wherein other spurious emission requirements predefined by the manufacturer are more stringent than those of the national radio commission.
When the spurious emission power corresponding to the frequency point with the maximum spurious emission power in the first optimal transmission spurious spectrum is greater than a preset power (for example, the power in the spurious emission requirement of the national radio commission or the factory-predefined power), or when the spurious emission power corresponding to the frequency point with the maximum spurious emission power in the second optimal transmission spurious spectrum is greater than a preset power (for example, the power in the spurious emission requirement of the national radio commission or the factory-predefined power), step 120 determines that the transmission spurious emission does not satisfy the preset condition.
Specifically, after the operating state of the transmitter is adjusted, if the transmission spurious meets the preset condition, the notch frequency point of the first variable notch module is adjusted. And after the working state of the power amplifier is adjusted, if the transmission stray does not meet the preset condition, adjusting the notch frequency point of the second variable notch module.
Optionally, in step 120, one or more of the notching frequency points of the first variable notching module and/or the second variable notching module may be adjusted, where the specifically adjusted number of the notching frequency points is determined so that the transmission spurs of the mobile terminal meet the preset condition.
Further improvement of the transmission spurs of the mobile terminal can be achieved by step 120.
In the first embodiment of the present invention, the mobile terminal includes a transmitter, a power amplifier, a first variable notch module and a second variable notch module, the first variable notch module is connected to an output terminal of the transmitter and an input terminal of the power amplifier, respectively, and the second variable notch module is connected to an output terminal of the power amplifier. Therefore, under the condition that the mobile terminal leaves the factory and has the transmission stray, the working state of the transmitter and/or the power amplifier can be automatically adjusted to improve the transmission stray of the mobile terminal, and after the working state of the transmitter is adjusted, if the transmission stray does not meet the preset condition, the notch frequency point of the first variable notch module is adjusted, and after the working state of the power amplifier is adjusted, if the transmission stray does not meet the preset condition, the notch frequency point of the second variable notch module is adjusted, so that the transmission stray of the mobile terminal is further improved. The embodiment of the invention can automatically improve the transmission stray of the mobile terminal under the condition that the transmission stray exists when the mobile terminal leaves a factory so as to enable the transmission stray of the mobile terminal to meet the preset condition as far as possible, does not need professional engineers to analyze and debug the mobile terminal which does not meet the requirements one by one, and greatly reduces the transmission stray problem debugging time and debugging cost of the mobile terminal.
Example two
A method for improving the transmission spurious provided by the second embodiment of the present invention is described in detail.
The method for improving the transmission stray is applied to a mobile terminal, and the mobile terminal can comprise a transmitter, a power amplifier, a first variable notch module and a second variable notch module, wherein the first variable notch module is respectively connected with the output end of the transmitter and the input end of the power amplifier, and the second variable notch module is connected with the output end of the power amplifier.
Referring to fig. 2, a flow chart of steps of a method for improving transmission spurs in the second embodiment of the present invention is shown.
In step 210, the operating state of the transmitter and/or the power amplifier is adjusted in the presence of a transmission spur in the mobile terminal.
Optionally, step 210 may obtain a first transmission spurious spectrum through data returned by a test instrument for testing spurious emissions of the mobile terminal, and determine that a transmission spurious exists in the mobile terminal when a spurious emission power corresponding to a frequency point in the first transmission spurious spectrum where the spurious emission power is maximum is greater than a preset power (for example, a power in a spurious emission requirement of the national radio commission or a power predefined by a manufacturer). Wherein the factory-predefined power requirement is less than the power in the national radio commission's stray transmission requirements. Specifically, the transmission spurious spectrum includes information such as spurious transmission power corresponding to the frequency point and the frequency point.
Specifically, step 210 may adjust the operating state of the transmitter by adjusting an operating parameter of the transmitter, and step 210 may adjust the operating state of the power amplifier by adjusting an operating parameter of the power amplifier. The working parameters of the transmitter can be the working parameters of the transmitter such as gain, supply voltage, bias current and the like; the operating parameters of the power amplifier may be gain, supply voltage, bias current, and the like of the power amplifier.
Optionally, after the operation state of the transmitter is adjusted in step 210, the transmission spur spectrum of the mobile terminal is the first optimal transmission spur spectrum. That is, in the process of adjusting the operating state of the transmitter, the spurious emission power of the frequency point with the maximum spurious emission power in the first optimal spurious emission spectrum reaches the minimum, and even if the operating state of the transmitter is continuously adjusted, the spurious emission power of the frequency point with the maximum spurious emission power cannot be smaller. Optionally, step 210 may obtain the first optimal transmission spurious spectrum by data returned by a test instrument testing the mobile terminal spurious emissions.
Optionally, after the operation state of the power amplifier is adjusted in step 210, the transmission spur spectrum of the mobile terminal is the second optimal transmission spur spectrum. That is, in the process of adjusting the operating state of the power amplifier, the spurious emission power of the frequency point with the maximum spurious emission power in the second optimal spurious emission spectrum reaches the minimum, and even if the operating state of the power amplifier is continuously adjusted, the spurious emission power of the frequency point with the maximum spurious emission power cannot be smaller. Optionally, step 210 may obtain a second optimal transmission spurious spectrum through data returned by a test instrument testing the mobile terminal spurious emissions.
Improving the transmission spurs of the mobile terminal can be achieved through step 210.
Optionally, the step 210 of adjusting the operating state of the transmitter and/or the power amplifier may include:
in step 211, it is determined whether the transmitter is a stray transmission source.
Optionally, the step 211 of determining whether the transmitter is a stray transmission source may include:
step 214, determining the first frequency point with the maximum stray transmission power of the mobile terminal.
Specifically, in step 214, after all frequency points in the first transmission spurious spectrum and spurious transmission power corresponding to each frequency point are obtained, the first frequency point with the maximum spurious transmission power is determined. Step 214 may also determine the first frequency point with the maximum stray transmission power in other manners.
Step 215, adjusting the working state of the transmitter and obtaining the variation value of the spurious emission power corresponding to the first frequency point.
When the working state of the transmitter is adjusted in step 215, the spurious emission power corresponding to the first frequency point is also changed accordingly.
In step 216, if the variation value of the stray transmission power corresponding to the first frequency point is greater than or equal to the preset power variation value, the transmitter is determined to be a stray transmission source.
The preset power variation value may be a value determined according to the spurious emission debugging data of a large number of mobile terminals.
If it is determined in step 216 that the variation value of the stray transmission power corresponding to the first frequency point is greater than or equal to the preset power variation value, the transmitter is determined to be a stray transmission source, and step 212 is performed, and if it is determined in step 216 that the variation value of the stray transmission power corresponding to the first frequency point is not greater than or equal to the first preset power variation value, the transmitter is determined not to be a stray transmission source, and step 213 is performed.
If so, the operating state of the transmitter is adjusted, step 212.
In step 213, if the transmitter is not a spurious emission source, the operating state of the power amplifier is adjusted.
If the transmitter is not a stray emission source, the power amplifier may be a stray emission source, and adjusting the operating state of the power amplifier may achieve improving the transmission stray of the mobile terminal.
In addition, if the transmit spur does not satisfy the preset condition after the adjustment of the notch frequency point of the first variable notch module, it indicates that the transmit spur cannot satisfy the preset condition by adjusting the operating state of the transmitter and adjusting the notch frequency point of the first variable notch module.
In step 220, if the transmit spur does not satisfy the predetermined condition, the notch frequency points of the first variable notch module and/or the second variable notch module are adjusted.
In particular, the preset condition may be a national radio commission spurious emission requirement or other spurious emission requirement predefined by the manufacturer. Wherein other spurious emission requirements predefined by the manufacturer are more stringent than those of the national radio commission.
When the spurious emission power corresponding to the frequency point with the maximum spurious emission power in the first optimal transmission spurious spectrum is greater than a preset power (for example, the power in the spurious emission requirement of the national radio commission or the power predefined by the manufacturer), or when the spurious emission power corresponding to the frequency point with the maximum spurious emission power in the second optimal transmission spurious spectrum is greater than a preset power (for example, the power in the spurious emission requirement of the national radio commission or the power predefined by the manufacturer), step 220 determines that the transmission spurious emission does not satisfy the preset condition.
Specifically, after the operating state of the transmitter is adjusted, if the transmission spurious meets the preset condition, the notch frequency point of the first variable notch module is adjusted. And after the working state of the power amplifier is adjusted, if the transmission stray does not meet the preset condition, adjusting the notch frequency point of the second variable notch module.
Optionally, in step 220, one or more of the notching frequency points of the first variable notching module and/or the second variable notching module may be adjusted, where the specifically adjusted number of the notching frequency points is determined so that the transmission spurs of the mobile terminal meet the preset condition.
Further improvement of the transmission spurs of the mobile terminal can be achieved by step 220.
Optionally, the step 220 of adjusting the notching frequency point of the variable notching module may include:
step 221, determining a target stray frequency point of the mobile terminal.
Step 222, adjusting the notch frequency point of the variable notch module to be the target stray frequency point.
For example, if step 220 adjusts the notching frequency point of the first variable notching module, step 221 determines one or more target spurious frequency points in the first optimal transmit spurious spectrum of the mobile terminal, and step 222 adjusts the notching frequency point of the variable notching module to the target spurious frequency points in the first optimal transmit spurious spectrum. And the target stray frequency point in the first optimal transmission stray frequency spectrum is a frequency point of which the stray transmission power in the first optimal transmission stray frequency spectrum is greater than the preset power.
For example, if step 220 adjusts the notching frequency point of the second variable notching module, step 221 determines one or more target spurious frequency points in the second optimal transmit spurious spectrum of the mobile terminal, and step 222 adjusts the notching frequency point of the variable notching module to the target spurious frequency points in the second optimal transmit spurious spectrum.
And the target stray frequency point in the second optimal transmission stray frequency spectrum is a frequency point of which the stray transmission power in the second optimal transmission stray frequency spectrum is greater than the preset power.
Specifically, if the transmit spur after adjusting the notch frequency point of the first variable notch module in step 220 does not satisfy the predetermined condition, step 213 also adjusts the operating state of the power amplifier.
Optionally, after adjusting the notching frequency point of the first variable notching module and/or the second variable notching module in step 220, the method may further include:
in step 230, if the transmission stray does not satisfy the preset condition, the current communication channel of the mobile terminal is changed to the target communication channel.
If the transmit spur does not satisfy the predetermined condition in step 230, it indicates that the transmit spur cannot satisfy the predetermined condition by adjusting the operating state of the transmitter and/or the power amplifier and adjusting the notch frequency point of the first variable notch module and/or the second variable notch module.
In step 230, the current communication channel of the mobile terminal is changed to the target communication channel, so that the current communication channel with the problem of transmission spurious can be avoided, the problem of transmission spurious of the current communication channel of the mobile terminal is eliminated, and the spurious transmitted by the mobile terminal is prevented from affecting other wireless devices.
The target communication channel may be an existing communication channel supported by a mobile terminal preset by a manufacturer.
Optionally, before changing the current communication channel of the mobile terminal to the target communication channel in step 230, the method may further include:
the problem of spurious emission of the current communication channel of the mobile terminal is prompted to be solved.
An instruction to change a communication channel is received.
In the second embodiment of the present invention, the mobile terminal includes a transmitter, a power amplifier, a first variable notch module and a second variable notch module, the first variable notch module is connected to an output terminal of the transmitter and an input terminal of the power amplifier, respectively, and the second variable notch module is connected to an output terminal of the power amplifier. Therefore, under the condition that the mobile terminal leaves a factory and has transmission stray, the working state of the transmitter and/or the power amplifier can be automatically adjusted to improve the transmission stray of the mobile terminal, after the working state of the transmitter is adjusted, if the transmission stray does not meet the preset condition, the notch frequency point of the first variable notch module is adjusted, after the working state of the power amplifier is adjusted, if the transmission stray does not meet the preset condition, the notch frequency point of the second variable notch module is adjusted, so as to further improve the transmission stray of the mobile terminal, and after the notch frequency points of the first variable notch module and/or the second variable notch module are adjusted, if the transmission stray does not meet the preset condition, the current communication channel of the mobile terminal is changed to a target communication channel, so as to eliminate the transmission stray problem of the current communication channel of the mobile terminal. The embodiment of the invention can automatically improve or eliminate the transmission stray of the mobile terminal under the condition that the transmission stray exists when the mobile terminal leaves a factory, and professional engineers do not need to analyze and debug the mobile terminal which does not meet the requirements one by one, thereby greatly reducing the transmission stray problem debugging time and debugging cost of the mobile terminal.
