Hi there, I tried recording the GSM broadacast data using the test_usrp_standard_rx code, but plotting it in Matlab does not look right at all. The exact command I used was: ./test_usrp_standard_rx -F 1976200000 -o /home/timur/GSM/openbts/Transceiver/output4.cfile -D 118 -v -M 20. I also made a recording from the same base station using usrp_rx_cfile.py, with the same decimation. Here are the results, plotted in Matlab: http://www.eecs.umich.edu/~timuralp/usrp_rx_cfile.jpg and http://www.eecs.umich.edu/~timuralp/test_usrp.jpg
I'm really not sure why the test_usrp_standard_rx output looks as it does. What other processing happens in usrp_rx_cfile.py after reading data from the USRP? What could I be missing here? Thank you. -- Cheers, Timur _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
