西蒙赫金的《自适应滤波原理》一书的matlab程序，现在继续上传第5.mvdr章的程序， 大家学习交流，觉得有用的自己下载，(西蒙赫gold Adaptive Filtering Theory matlab program book, and now continue to upload the first chapter 5.mvdr procedures, everyone learning exchanges, and find useful to download their own,)

This an adaptive receiver for a direct-sequence spread spectrum (DS-SS) system over an AWGN channel. The adaptive receiver block is modified from the LMS adaptive filter block in DSP Blockset. For DS-SS signal reception, the adaptive filter needs to have multi-rate operation. The input sample rate is equal to chip rate and the output is at symbol rate. Two rates are related by PG, processing gain
