| 摘 要： | 通过小波阈值方法可以去除语音中的噪声,但它的结果中会出现诸如Pesudo-Gibbs现象之类的情况.为消除此类情况,将平移不变量小波变换引入到语音信号去噪中,并结合阈值方法进行去噪处理.经过仿真实验,证明这种方一法比一般的阈值方法有很大改进,提高了信噪比.

| Abstract: | Through wavelet threshold method can effectively eliminate the noise of acoustic signal.However,some cases such as Pesudo-Gibbs phenomena would appear in its result.In order to eliminate this phenomena,translation invariant is presented in the acoustic signal denoise.Moreover,the threshold method is combined to eliminate the acoustic signal denoise.Results of experiment show that the given algorithm is much better than the common deniosing methods and the SNR has been increased. |
