BPSK modulation in wireless sensor network over Rayleigh channel

Hi all, I have a matlab code that calculate the BER of bpsk modulation over a rayleigh channel I want to apply it to a sensor network ,how do I proceed. matlab code: % Script for computing the BER for bpsk modulation in a % rayleigh fading channel clear N = 10^6 % number of (...)

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 implement qpsk in mimo system, and increase receive and transmit antennas

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 (...)
