Discuss the case where there a multiple (two) transmit antennas and multiple (two) receive antennas resulting in the formation of a 2x2 Multiple Input Multiple Output (MIMO) channel. We will assume that the channel is a flat fading Rayleigh multipath channel and the modulation is BPSK.

The equalization scheme used is Zero Forcing. As expected, the simulated results with a 2×2 MIMO system using BPSK modulation in Rayleigh channel is showing matching results as obtained in for a 1×1 system for BPSK modulation in Rayleigh channel.

how can be create a channel for 10 by 10 mimo using raylrnd function for zeroforcing

Thank you very much for this codes.
I would like to know if you have any suggestion if we would like to make a Massive MIMO with several Tx Antennas and Rx Antennas?

Thanks

There is something wrong with the code.
hInv = hCof./hDen; % inv(H^H*H)
for i=1:N/nTx
hInv(:,:,i)=conj(hInv(:,:,i));
end
The performance will be much better.

Hi every body,
I would like to know how I can generate Rice samples in Matlab.
Thanks for your response.
