| Abstract: | 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. |
| Keywords: | adaptive digital filter noise removing fixed-point DSP |
