OFDM PSD - disa...@gmail.com - Oct 23 19:33:13 2007



hi all, i'm trying to plot ofdm normalized (dBr) psd after ifft function.
i.e:
 carriers=NFFT.*ifft(tx);
 %plot normalized PSD
 
i've tried pwelch(), psd() and their varients but my results do not match the theory.
 
i'll appreciate some help on the subject.
 
thanks.

Are you plotting the psd with the time domain samples???

Thanks and Regards,
