Hi Matt/Micheal I have two XCVR2450 Trancievers.I have also two wire antennas connected to each. So,I have separate transmit and recieve paths, but I am using a single USRP.
I am using them the transmiter and reciever boards at almost the same frequency. I am transmitting at 2.45GHz and I expect to recieve a reflected signal at a frequency of 2.45GHz + Doppler shift. So, what do you suggest? Thanks!
