Hi i have a signal that periodically repeat a structure, i need to find in that signal the structure, which i know previously. For doing that i was thinking about doing the correlation between the big signal and the signal of interest but i do not know how to implement it in matlab.
please help...

Hello!
I am working with the signal of a picture. It is
Synchornization ( 7 square pulses 1040Hz) total of 39 words
Space Data ( 47 words)
Image ( 909 words)
telemetric 45 words
Synchornization b(7 square pulses 832 Hz duty ratio 60%) total39 words
Space Data (47)
Image (909)

Hello, i want to remove the dc of my signal in matlab but i do not know if i have to implement a filter center in zero or sustraining the main value of the signal.
thanks
Hello, i have downloaded a code from matlab file exchange but i do not understand how it works, can someone explain it to me? It is used for demodulation FM. thanks
function x = FMdemod(y,beta)
[r, c] = size(y);
if r*c == 0
y = [];
return;
end;
if (r == 1)
y = y(:);
len = c...
Hello everybody, a need to produce a Digital FM demodulation in matlab but i am a bit confuss, because i have always studied that fm is an analog modulation so why digital?
how can implement the digital fm demodulation?
where can i find the code?
thank you very much
Hello I have some data saved in a .wav file. It is modulated in FM consequently i need to demodulate it but i do not know how to implement a FM demodulation.
There exists any models of FM demodulation in wav files?
toopen the wav file i should use wavread?
I do not know how to start.
