If i want to make 2x2 MIMO than how many USRP module need ??
I have USRP 2920 module.
Can I Make The Transmitter and Receiver with the single Module ?
for 2920 USRP to build 2x2 MIMO you have to use 2 USRP Nodes , you can connect between them Using MIMO Cable that will provide the Connectivity and Synchronization between the Nodes .
Regarding your question about using both transmitter and receiver for the same node at the same time , actually it is possible , but there is no theoretical reference for that .
