摘　　要：自适应噪声消除技术在信号处于噪声很强的环境中时,可以非常有效地将噪声去除掉。而DSP是一种高速、高性能的专业数字信号处理器,用DSP实现自适应噪声消除,其具有很好的实时性和处理精度。在此完成了基于DSP的自适应噪声消除系统,有效地消除了信号中的噪声。Adaptive noise cancellation is used to remove background noise from useful signals. This is an extremely useful technique where a signal is submerged in a very noisy environment. DSP is a kind of high speed and performance professional digital signal processor. Using DSP in adaptive noise cancellation system, real- time control and high precision can be achieved. In this paper,an adaptive noise cancellation system based on DSP is designed,and noise in the signals is decreased efficiently.
