Actually I want to obtain a good BER result. But I couldnt obtain a good BER result and I also want to implement and show a OFDM frequency spectrum signal. and i want to obtain a time domain signal.I must obtain the results like the last two attachment (freq and time )But I cant , I am showing all subsystem block please help me this is my bechalor Thesis I want to graduate !!!
these are some parameters about this simulation what are drawbacs Could you tell me ?
