Hello, I am testing the OFDM trunk code 9798 in openSUSE 10.3 (i586). I run the benchmark_ofdm_tx.py script while having connected the USRP to a spectrum analyzer and to my surprise, using the default parameters of the script (those are: Modulation Type: bpsk, FFT length: 512, Occupied Tones: 200, CP length: 128, Tx amplitude: 200)
The spectrum shape that I get corresponds more to a single carrier modulation than to an OFDM signal (I see just 4 peaks spaced around 4MHz). I cannot see where all the subcarriers are gone! There is not any error message prompted or apparently any reason so that this is not working. I would really appreciate some help with this issue. Thanks in advance. -- Natalia Olano _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
