Maybe you could inject a stable frequency near the wanted RX frequency.
Say a few Mhz away from the 1.57542e9 you want to receive.
Then you could use this in the output to remove the jitter and LO drift.
for example:
inject 1600000000 Mhz (=25 harmonic of 64MHz) at the input (after
the saw filter)
This will result in 24.58 Mhz +jitter +LOdrift at the input of the
USRP (after dbs_rx downmix)
I wonder if any 25th harmonic is already in the signal, by virtue
of leakage within the USRP itself? That would be great.
