任何能量有限信号可以用Ｍ－频带紧支撑正交小波基展开，这有助于研究快速信号处理算法和高效编码算法。本文设计了一种基于Ｍ－频带正交小波变换的宽带语音编码算法，该算法语音质量好，编码时延小。

Any finite energy signal can be expanded in terms of Mband compactly supported orthogonal wavelet bases, it is helpful to the development of fast signal processing algorithms and high efficient coding schemes. A wideband speech coding algorithm based on Mband wavelet transform is designed, with good speech quality and low coding delay.
