In this paper, we propose low complexity realization of nonlinear acoustic echo cancellation. Generally, it is assumed that the acoustic echo path in hands free telecommunication systems is a linear system. However, the acoustic echo path in modern cellular phones has nonlinearity because the influence of nonlinear distortions of the low cost audio equipment is very large. In order to solve this problem, the nonlinear echo cancellation that includes the linearization system has been proposed… CONTINUE READING
