noise in mimo ofdm
Hi,
I'm trying to simulate a mimo ofdm system but i'm not sure how i should be adding the noise.
Should it be like this:
no=10.^(-snr/10)*(fftsize);
because at the ifft i'm multiplying by sqrt(fftsize), and when i receive the signals i add the noise. Then when i take the fft i divide by sqrt(fftsize) again.
thank you for your help.
