摘要
基于小波的多分辨率分析原理提出无偏风险阈值估计算法 ,并应用于语音信号去噪处理 ,实验结果表明该算法在低信噪比的语音信号中去噪效果良好。
Based on the multiresolution analysis theory of the wavelet, the algorithm about using unbiased risk estimate is proposed to de-noise the noisy speech in this paper. The experimental results show that this algorithm has better de-noising ability in the speech signal of the low SNR(signal noise rate).
