[Discuss-gnuradio] Re: MIMO and USRP

[john boon]

hi all,
       Thanks for earlier reply to my mail. i am gathering all details and suggestions at implementing mimo 2x2 system on USRP board.


                |---->  SIDE A (Tx/Rx) ---> transmitting Antenna 0 symbols
USRP  -----|
                |-----> SIDE B (Tx/RX) ---> transmitting antenna 1 symbols

As gnuradio forum list is vast and so also supporting forums and discussion groups. Can anyone point me any resource on implementing MIMO (diveristy and multiplexing modes) schemes on usrp board (both .py or .cpp) . All along i have seen single transmit and single receive.Py and .Cpp codes, but not dual transmit or dual receive .py and .cpp codes. One good reference which i encountered to start is dualtx.py at

https://www.cgran.org/browser/projects/ucla_zigbee_phy/trunk/src/examples/cc1k_cc2420_dualtx.py

so my question is (i am not good at .py coding.so i need little time to understand and code it), is this file good one to start with or if there is any file (more relevant to mimo implementatiom) which can kickstart coding at great level.

pls suggest me..my initial and final goal is to write Mimo Tx and Rx code in c++ and make use of IT++. if any existing resources are there. i will be very thankfull..if someone can point it to me..


thanks and regards
john
