Hello,
I sampled an FM station and created a sample file with one second worth of
samples:
$ ./usrp_rx_cfile.py -d 256 -f 97.9M -N 256k fm1.out
This works; I can listen to the audio just fine using:
$ ./wfm_rcv_file.py fm1.out
Now I want to input the samples to octave:
octave> v = read_complex_binary("fm1.out", 256000);
The problem is that the samples don't look right to me:
octave> v(100:105)
ans =
-14 + 21i
-14 + 22i
-19 + 18i
-22 + 13i
-25 + 8i
-27 - 3i
Most samples seem to be integers between -35 and 35. Besides, I *always* get a
spike at around sample 500:
v(520:525)
ans =
-125 + 296i
220 - 603i
-478 + 1330i
932 - 2711i
5033 + 2437i
-2243 + 7548i
No matter how many I re-run the usrp_rx_cfile program, I get similar results. Is
this normal?
