Hello, GNU Radio users, Very long time ago, USRP 1 was not suitable for half-duplex communications because USB 2.0 interface is too slow to achieve it. But now, there are USRP embedded and gigabit ethernet supporting USRP series. In my opinion, thus, half-duplex communications might be achievable nowadays.
I am curious that there is a project which implements half-duplex communications. If there is, how many USRPs, daughterboards and antennas are used for each node? Can I find such a project in pybombs? In my guess, a half-duplex communication application can be built from both USRP sink and source being placed in one flow graph. But I have no idea of the rest of the flow graph. Should the flow graph open loop or closed loop? Is there a special configuration or tweak on USRP or GNU Radio required to achieve half-duplex communications? I apologize if my question sounds quite vague. Regards, Jeon.
