It scrambles up your bits (makes them white in
Hi Jack,
Answer to question 1:
I believe the whitening option randomises the data bits so that the PAPR
(Peak-to-Average Power Ratio) is reduced.

Hi,
Could someone please answer following questions of mine :
1) In
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 o
Hi,
I was going throught the code of wfm_rcv.py. The
source is created using
src = usrp.source_c (0, decim) (1)
Since the default mux settings are 0x32103210 this
means connect DAC0 to I0 and DAC1 to Q0(inputs of
DDC0).
1)Why do we need input from 2 DACs, since the RF front
end ou
Hi,
I am using the usrp_siggen.py program to transmit a
complex signal to the USRP. The interpolator on the
transmit side generates an I and Q part for my signal
and I transmit it via DAC0 and DAC1.
1)Is DAC0/DAC1 connected to J48/J49?
Now I connect J48 to J19 and J49 to J18.
2)Is ADC0/ADC1 co
