The way I'm doing it is the following (please
correct me if there is a fundamental error in assumptions): I am
actually using an RSSI circuit that is receiving the power from
the USRPs/antennas, and I'm determining whether the phase offset
is the same based on that RSSI value. For example, I run the
flowgraph once, and I get an RSSI value on the other side of 2.5
mW, but when I run the flowgraph again, it produces an RSSI
value of 9.5 mW. In my mind, if that offset was constant, then
it would have produced something around 2.5 mW again. I know
this adds another variable to the mix, but I have confirmed the
accurate functioning of the RSSI circuit/receiver as well as the
static nature of the channel, so its reading is very reliable.
Could you describe this RSSI circuit? Normally, they're only
sensitive to amplitude, not phase.
