## Help required for 3*3 mimo system using ZF equalizer

Hi Friends I am working on analyzing the BER of MIMO system using Zero force equalizer in rayleigh channel. I implemented 3*3 mimo system using bpsk modulation in matlab but unfortunately i am not getting the accurate curve in the plot. The figure is attached, please anyone who can solve my this problem. Thanks

## OFDM transceiver with rayleigh channel using Standard PDP in matlab

I have built an OFDM transceiver with rayleigh channel using standard PDP's Like EPA,EVA and ETU.The problem is I am getting very high BER even for bpsk i.e 50-60 % or higher bits in error.Scatterplotting confirms OFDM transceiver blocks include: ---- Random Data -- Modulation(bpsk,QPSK,QAM) -- Serial2Parallel -- IFFT -- (...)

## how to send transmitted power of a signal along with the signal in matlab

how to send transmitted power of a signal along with the signal in matlab......Need help for Example the receivec signal is y =hx+n if x is bpsk transmitted signal h is rayleigh fading channel n is AWGN how can I incorporate the transmitted signal power in this formula?

The reason is that 1 simplifies analysis. In any case, the variance of h will be a scaling factor. For example if E=a, then the average BER over rayleigh fading channel and using bpsk is given by: 0.5\left which shows that a does not affect the diversity order of the system, which i

## I did OFDM/rayleigh simulation but what theory BER equation to compare with?

I did simulation of OFDM over rayleigh channel (bpsk). But I am confused what theory BER equation I should use to compare this simulation result with? Can you please let me know or give me the theory equation to use. So I can compare them both and see if my simulation is correct or not. Thank you so much.

## BPSK BER in rayleigh IN MATLAB : why noise and channel is the same in matlab.

I have a look on people's matlab on bpsk BER over rayleigh channel. I don't understand why noise and channel are the same as shown below. so rayleigh channel is the same as noise then? Can anyone explain it to me please. noise=1/sqrt(2)*(randn(1,N)+1i*randn(1,N)); %AWGN noise with (...)
