Could someone please answer following questions of mine :
pkt = ofdm_packet_utils.make_packet(payload, 1, 1, self._pad_for_usrp, whitening=True)
what is whitening?
2) In gr.fft_vcc(fft_size,forward, window, shift=false)
What is window vector?
3) in ofdm_mod there is a portion of code having comments:
Use freq domain to get doubled-up known symbol for correlation in time domain
Can you please explain this part.
Thank you in advance.
