用MATLAB实现的标准卷积的算法源程序

 
x=[3,11,7,0,-1,4,2];nx=[-3:3]
[y,ny]=sigshift(x,nx,2);
w=randn(1,length(y));
nw=ny;
[y,ny]=sigadd(y,ny,w,nw);
[x,nx]=sigfold(x,nx);
[rnx,nrxy]=conv_m(y,ny,x,nx);
subplot(1,1,1),subplot(2,1,1);stem(nrxy,rxy);
axis([-4,8,-50,250]);xlabel('lag variable 1')
ylable('rxy');title('crosscorrelation:noise sequence 1')
