Looks like there is a random phase. Every time you start, the phase of the clock maybe different. Hence when you plot the signal, it's going to be different. I can observe the same random phase in my BPSK program. Bakshi, Arjun via USRP-users 于2017年9月1日周五 下午2:48写道: > Hi all, > > > Had posted abou

Hi all, Had posted about this before, but focusing on 1 simple case here. I'm observing a change in a wired channel every time I restart my flow graph. I'm using 1 USRP + WBX board, i.e. tx and rx on the same USRP. So time/frequency sync should not be a factor, I believe. I simply do: start
