| Abstract: | The adaptive echo canceller (AEC) is implemented by adopting a single chip high speed digital signal processor, TMS32010. The adaptive vari-ant step length algorithm is used, which makes it possible to achieve both fast convergent speed and less remaining error. For perfect realization of the full-duplex operation, the threshold detecting technique is also used.The experiments including on-line test show that the performances are better than the standards of the CCITT G.165. |
