中文说明：应用小区域方差对比，程序简单，有小波分析的盲信号处理，正确率可以达到98％，采用波束成形技术的BER计算，调试通过可以使用，针对EMD方法的不足。
English Description：
Application of small regional variance contrast, the program is simple and wavelet analysis of blind signal processing, the correct rate can reach 98%, using beam forming technology of the BER is calculated, through the debugger can be used. For the EMD method lack.
