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 again, I found the editing details for M-QAM here:

17 May 2013 BER of OFDM in rayleigh enviroment using BPSK modulation script utilizing communication toolbox functions. Author: Mohammad Tahir n1ng, Bruno

Hi Mohammad,

When simulating 16-QAM, there is an error:

??? Subscript indices must either be real positive integers or
logicals.

Error in ==> BER_OFDM_RAYLEIGH at 32
pilot_ins_data=[zeros(nsym,6) par_data(:,[1:nbitpersym/16])
zeros(nsym,1) par_data(:,[nbitpersym/16+1:nbitpersym])
zeros(nsym,5)] ;

How may this be resolved?
