I have found the answers. http://nutaq.com/en/blog/multi-channel-synchronization-fpga-based-daq-systems http://nutaq.com/en/blog/brief-overview-frequency-synchronization-ofdm
On the Nutaq platforms (ZeptoSDR, PicoSDR) you can control VCXO voltage DAC from GNU Radio (and from FPGA user logic) to implement carrier frequency offset correction. Thanks everyone for your help. _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
