08 Mar 2011 BER of OFDM in rayleigh enviroment using BPSK modulation script utilizing communication toolbox functions. Author: Mohammad Tahir

Because we have assumed ideal channel estimation in this case and the improvement of OFDM over BPSK rayleigh will be seen when we have imperfect channel equalization of frequency selective channel which cause ISI at the receiver. (please ignore the first one due to typo)

Hi,
Your code specifies sample time is 1/10000 in rayleighchan. However, I think the sample time of the code is 1/80. Is my understanding wrong?

> h=rayleighchan(1/10000,10);

what are the terms: 10log10(52/64) and 10log10(64/80) and the minus term in the snr definition?

Why OFDM RAYLEIGH is equal to the BPSK RAYLEIGH , should not it be better?

please help me
