I have a simple FX-correlator Gnu Radio flowgraph that I’ve been experimenting with, and I tested it today against the latest LimeSDR drivers and firmware.
It was easily able to achieve 2 channels at 16Msps per channel, producing various observation
products including FX correlation, spectral, and total and differential power, all in real-time.
I’ll write this up as one of our “memo” series here at some point:
