I am going to work on my project that is including two adalm pluto sdr ad9363 rev C with enabled 2r2t mode. The aim of the project is using 4 antennas direction of arrival estimation and digital beamforming systems. Each device use its own 40 MHz crystal oscillator it causes frequency and time offset. If i know right, clock synchronization is not allowed for this model. There may be different approach to compensate that phase difference between two devices using pilot based software synchronization. I need to synchronize the receiver side this approach is useful but not enough to do doa and beamforming calculation since carrier frequency offset has never been reached 0 value. Is there any different way to make this two device phase coherence without changing the sdr model to any other model like fmcomms5 ?
I also reach out approximately 7000 kHz frequency offset between two device. Maybe the reason that cause frame drop is occuring due to the usb.
