We bring forward the method through compare the two projects adaptive spectrum enhancement and wavelet analysis which combines the wavelet analysis and the adaptive theory and have the information of several frequence bands being the reference input signals to reach the adaptive processing and restructure of speech signal by making use of merits of the two theories 通過對比自適應譜線增強和小波變換的兩種方案,提出了把小波分析理論與自適應理論相結合,利用兩種理論的優勢,用小波分解后的若干層頻段信息作為參考輸入信號,實現語音信號噪聲的自適應處理和重構。
