I try the benchmark_ofdm_* in the ofdm example (gnuradio trunk v10991) but unfortunately i always receive no data and TIMEOUT. did i need to modify somewhere in the code? is there any ofdm example in any trunk version that work? thanks adib -- View this message in context: http://www.nabble.com/GNU-Radio-OFDM-Theori-tp22697706p23443430.html Sent from the GnuRadio mailing list archive at Nabble.com. _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
