基于DSP的回声消除系统设计与实现

Design and Implementation of Echo Cancellation System Based on DSP

在通信行业•日渐发达的今天,回声消除的应用十分广泛。为了满足自适应滤波器回声消除系统实时性和精确性的要求,本文选取具有强大信号处理能力和控制能力的数字信号处理器(digital signal processer,简称DSP)作为核心算法的处理芯片来完成回声消除的硬件实现。

Nowadays,with the development of communication industry,echo cancellation is widely used.In order to meet the real一time and accuracy requirements of the adaptive filter echo cancellation system,this paper chooses the digital signal processor(DSP)with strong signal processing and control capabilities as the processing chip of the core algorithm to complete the hardware implementation of echo cancellation.
