%X The complex double channel system is always used in the traditional adaptive noise cancellation method. Aiming at the shortcoming, this paper proposes that the delay of original input signal is selected as the reference noise input, and then designs a single-channel system by using a DSP processor which can self-adaptively filter the voice signal. The system achieves the acquisition, transmission of voice signal and self-adaptively filters the noise signal,by seting up by TMS320VC5509 DSP and audio chip TLV320AIC23. The experimental results show that the self-adaptive filtering system can effectively separate the useful signal and noise and get a perfect playback effect.
