I am building an OFDM transmission and reception system, but I am
having difficulty recovering the BPSK constellation during reception,
as the signal has a large phase rotation. I use a PLL before symbol
synchronization, but I have not been able to solve the phase rotation
problem.
Does anyone have any suggestions?
I use an OFDM signal generated by an MG3700 (Anritsu) and the
programming is done in Python.
I appreciate any suggestions in advance.

I will note that this type of question isn't specific to USRPs, but more
a DSP question. You might fruitfully repeat your question
on the discuss-gnuradio mailing list -- there may be more generic DSP
people there than here.
I don't know much about your *specific* case, but in general, one cannot
expect two randomly chosen devices to be
in-phase with respect to each other, so if your receiver expects that
it is in-phase with respect to the transmitter,
without any kind of phase-estimate and correction, it will routinely
not work.
