Synchronization using USRPs

GNU Radio
1

Dear All,

I intend on implementing cooperative beamforming techniques using USRPs
(two USRPs send precoded versions of the same symbols to null out
transmission at certain directions). I need the two USRPs to be almost
perfectly synchronized in time and carrier frequency. What are the
available time synchronization and local oscillator synchronization
techniques using Gnuradio?
