通过子带脉压技术，对大宽带信号进行频带分割，分别进行子带匹配滤波，最终实现大宽带的AD采样。-Through the subband pulse pressure technology, divide the big broadband signal ,through matched filter respectively, and finally achieve big broadband AD sampling.

语音信号子带编码源程序,用matlab做的 不错的源码 很好-Speech signal source code, subband coding matlab do good source is very good
