My first column of circulant matrix should be like this...Pls help

H_k,j = [h_k,j(0)......h_k,j(L-1) 0 ............0]T

where h_k,j is the channel impulse response from jth transmit to kth receive antenna

H=[ H_k,0; H_k,1.......H_k,Nt-1]

Nt=2;L=65

Pls share ur ideas

[Janet]

H_k,j = [h_k,j(0)......h_k,j(L-1) 0 ............0]T...This is first column and it should be keeping on circulating and the size of matrix is M x M

You can use my circulant matrix generator, or you can build it in a variety of ways.

i am a newbie..can u pls say me how to use it?

[John D'Errico]

I'm sorry, but even a newbie can surely read the help, and if you can't, then you need to start with a basic MATLAB tutorial. The help on that function (I wrote it, so I know) will tell you no less than I would if I were to give you a complete in-depth explanation here. And there are several examples in the help! The best thing a newbie can learn is how to use the documentation provided.
