Abstract:
In this paper an improved single and doubletalk echo canceller system is proposed in conformity with the ITU-T recommendation G.168, implemented on a Motorola SC140 digital signal processor. The performance of the adaptive system by comparison between convergence and error attenuation of different kinds of LMS (Least Mean Square) algorithms was studied. MatLab simulations results led to the conclusion that the GNGD algorithm satisfies the conditions presented above
