Ok. I found another problem in my code. The transmit_path has a
multiplier in it that was set to 200 (it could go up to 32768). This
was for the original USRP, but I think UHD needs a signal with
magnitude<=1. It seems like the signal was probably clipping. I
changed the magnitude of the multiplier and fiddled with the gain
parameters a bit. I'm now able to get the standard boxcar that I
expect for OFDM. There's still a spike at the center frequency though,
I don't see a gap.
Thanks,
Morgan
If you're doing these tests over-the-air, is it possible that there's a
signal on TV channel 44 around you?
Channel 44 starts at 650MHz.
