Hello everyone, I was wondering if someone could either point me to an example or give me some tips on how I can get setup gnuradio to do simultaneous transmit and receive on multiple channels. At the moment, I just need to transmit on one channel but need to receive on 4 independent channels.
I am running gnuradio 3.2.2 on Ubuntu 9.04. I have a USRP-1 with 2 LFRX boards and 1 LFTX board. Following the USRP code examples that came with gnuradio, what I've been able to do successfully so far is: --simultaneously transmit and receive on single channels. --receive on 4 independent channels. If I then take my working multi-channel receiver and just add a line to create a transmitter sink object with usrp.sink_c(), all 4 receive channels show sequences of alternating 0, -1 values instead of the digitization of the signal that I'm putting into the input channels. I don't have this problem if I modify my receiver to receive on just one channel -- I can then transmit and receive simultaneously without problems. Any ideas on what I'm doing wrong here? thanks Young _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
