中文说明：我已经编写了MATLAB代码的分块矩阵，可以用来阻止所需的信号从噪声信号。
English Description：
I have written MATLAB code for blocking matrix which can be used to block desired signal from noisy signal. You can use this blocking matrix in generalized sidelobe canceler (in below path ) to block speech signal and generate noise reference signal. And this file also contains LMS filter which can be used in adaptive way to cancel out noise
