Thanks Marcus! Is it possible to synchronize the usrps using individual gpsdo modules for each board or is a central distribution system (like the octoclock) necessary? Hello Muhammad Shahmeer Omar, with neither an external signal or a GPSDO, this is physically impossible. I think with

Hello all, Ive been trying to achieve transmit time synchronization for over a month now using GNURadio and USRP B200, and so far i have had limited success. I could not find alot online. My question is simple. Is it possible to achieve synchronization between two USRPs without using an external s

Hello all, I am trying to implement a multi-relay cooperative network using gnuradio and USRP B200. I cannot figure out how to synchronize the relay transmissions using GNU-Radio (without editing FPGA code or using external clock source). I created an out of tree module derived from the tags_demo

hey. I am trying to synchronize transmissions from multiply relays using gnuradio and usrp b200 radios. I would prefer to achieve this in GRC but i cannot figure out how to to do this. If it is not possible in GRC, then please tell me how i can achieve synchronization using python code. Thank you.
