This paper introduces a steganographic approach to embed data on compressed speech bit stream in order to hide secret data. This method may be used by any kind of encoded bit stream, but this research concentrates on full rate (GSM 6.10) encoded bit ...
In the digital cellular environment, acoustic background noise and channel bit errors (both bursty and random) may severely degrade the performance of speech coders such as the current European GSM full rate standard. This paper presents a CELP-based, ...
Today, the primary constrain in wireless communication system is limited bandwidth and power. Wireless systems involved in transmission of speech envisage that efficient and effective methods be developed (bandwidth usage & power) to transmit and ...
