摘 要：
The paper introduces acoustic echo cancellation algorithm that is based on the improved and variable step size NLMS and it's DSP implementation. The echo canceller that is designed and implemented with the TMS320C5402 DSP is used in terminal in a telephone conference, the application in test has got a good result.
