Hi , I implement an OFDM System with Simulink , by regular search i found that sent one , but when i run it to get BER Vs EbNo , it get high curves and values rather than expected to be.
i use QPSK as modulation technique , so as i know the BER curve of OFDM must be the same as QPSK system ,
is that true , and if, what is the wrong in results,
waiting ur reply ,PLZ.

Re: BER of OFDM System

I suggest you post this in the digicom forum to get more replies.

But yes, OFDM QPSK should be the same as simple QPSK for AWGN and Fading channels.

Thank you for your help , i will sent it to communication part .
 

Re: BER of OFDM System

Recomm u have done a good job here, i am actually carrying out the same project but showing the trade off between different modulation schemes. I also need to add some enhancement like convolutional encoder, interleaver and viterbi decoder wv deinterleaver wv Rayleigh multipath fading. I av been getting errors so far, please kindly assist me omotayour06@yahoo.com. I have just less than a month for this. Tanx
