Hello

In my OFDM system, I need to apply a Hamming and Blackman window in frequency domain. My simulation is on Matlab.

I've done a FFT of this window and did its convolution with my data in freq domain, but I'm not getting the desired results. :-(

Can anyone help me to do this the correct way ?

Thank you.
 

Hi,

In your code,is the window length equal to your transform length ?

Requires more information on what do you mean by not getting desired results ?
