Hi all, I have been trying to generate (from a random 0-1 source) and send a simple QAM signal from one side, receive and save as .dat file in another.
Then I try to recover the signal I sent in Matlab/Octave. My method is to first use read_complex_binary() to extract points, and sample 2000 of them for later use. Then (I assume they are for the time domain) I convert these 2000 points with abs() and fft(). However, what I plot is completely different from the actual signal I sent. What exactly dose the .dat data mean? Time domain. or frequency domain? Could we recover the same signal from this? I am still very new to gnu radio, and I would appreciate any help. Thank you. _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
