Hi all,
I have some problems in simulating the OFDM using
matlab. I will list them one by one.
1). Normailsation of the signal after ifft & fft.
Do we have to multiply by any factor after taking the
ifft and fft in the matlab?. Please explain me about
this for the OFDM symbol with Useful Subcarriers.
2). Finding the NoiseVariance in to create the AWGN
Noise Samples. please explain me for the OFDM system
having useful subcarriers .
Thanks in advance.
Jasan
