    Performance of BER vs SNR with increased NB of antennas

    I have done the MIMO simulations to see the performances of BER vs SNR with increased NB of antennas with different receivers(matched filter, decorrelator, MIMO and MIMO-SIC), I have submitted the plots below, whether anyone can check whether they look like normal or not. If not, what I should still improve. The below figures are done in high SNR regime, I have also done the low SNR regime part, but here it seems unnecessary to summit them.

    First figure, with receiver MMSE, from below to top, 2by2, 3by3,......, 8by8


    Second figure, with receiver Decorrelator,


    Third figure, with receiver Matched filter,


    Last figure, with receiver MMSE-SIC,


    It looks like the BER are a little bit high, anyone has any idea to improve the BER performance.
    Thanks.

    Re: Performance of BER vs SNR with increased NB of antennas

    I like to know Simulation parameters of MMSE -SIC receivers.

    What type of channel and modulation technique used?

    Performance of BER vs SNR with increased NB of antennas

    I use Rayleigh fading channel,
    for modulation, for 2by2 I use 4QAM, 3by3 I use 8QAM,
    ......, 8by8 I use 2^8QAM.
