Hi everyone, I am doing Masters thesis in multiuser detection in OFDM. 
The basic model is y=hx+v . y is the mixture signal recieved by the 
rxr, h is the channel matrix, x is the original signal txd, v is the 
noise added in the channel. Each rxr Antenna has to separate its 
corresponding user signal from the mixture of signals.

Can I have the Matlab code for this. I have written the initial OFDM 
code but i am having problem working with multiple Antenna transmission.
