Abstract：An improved adaptive filtering algorithm is proposed in this paper, and the convergence of the algorithm is analyzed. As an example, the new algorithm is used to cancel echo for the chaotic modulation communication systems experiencing echo channels. The results by computer simulation indicate that the improved algorithm has faster convergence speed and higher accuracy of computation. In addition, the new algorithm is steadier in the case of low SNR.
