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.
