I am using 3 USRPs (USRP N210 ). I run example program "benchmark_rx.py " and "benchmark_tx.py " in /gr-digital/examples/narrowband/. I performed experiment on 2 USRP's(A,B) at a time. so A-B and B-A 2 channels for 2 USRP. when I send packets from A-B "psk" modulation scheme gives best(171/171)* performance while same is not true for B-A(171/0)*. while "gfsk" scheme gives good performance from B-A(171/171)*. Can anybody knows why different modulation scheme gives different result on different channel ? Is it related to USRP synchronization ? Can we perform packet level debugging in USRP ? How can we find the cause of this problem ? Or is it implementation related bug in GNU-radio? * : (n_rcvd/n_right) n_rcvd => received packet,n_right => correct received packet
