摘　　要：将基于DSP的自适应滤波器用于通信系统,利用自适应滤波器的通带始终和输入信号频带宽度自适应相匹配的特点,实现通信系统中的噪声消除。实践证明较好地实现了噪声消除,能够达到改善通信质量,增加通信距离的效果。In this paper,the adaptive filter based on DSP is used for the communications system.That the passband of adaptive filter always matches the bandwidth of input signal automatically is conducive to eliminate noise.It can reduce noise infection effectively,improve communication quality and increase communication distance.

关 键 词：自适应滤波器 噪声消除 定点DSP
