Hello. I have the 16-FSK modulated signal.
[y,fs] = audioread('signal.wav');
And then I have to recover bits that are coded by different frequency values. I was trying demodulation:
fc=6; %default
M=16;
fskdemod=comm.FSKDemodulator(M, fc, 'SamplesPerSymbol', 4, 'BitOutput', true);
z=fskdemod(y);
But I don't think the output is correct. Can you give me any clue?
And there is fragment:
