Abstract
Modern radio frequency transceivers for wireless communication standards operating in frequency division duplex suffer from an unwanted Tx leakage signal. In combination with carrier aggregation this might harm the receiver in form of a so-called modulated spur interference. Different digital interference cancellation techniques have been proposed but suffer from a slow adaptation rate due to the high correlation of the involved Long Term Evolution (LTE) signals. This work derives and analyzes a new form of the Least-Mean-Squares (LMS) algorithm that incorporates knowledge of the signal statistics. Simulations show that the presented algorithm can effectively improve the cancellation and adaptation performance for real world interference scenarios.
