Abstract :
This paper presents a nonlinear echo canceller implementation running on a digital signal processor (DSP). A nonlinear channel is equalized, by using a set of linear dynamic system followed by a nonlinear static map. The proposed scheme is implemented on a general purpose DSP with floating point arithmetic.
