I don't know how to analyze this signal and use proper filter for it. I work in matlab, function sptool. I don't know how to identify modulation pulse length, characteristic interval length, modulation signal frequency, carrier signal, modulation signal type, modulation type. Also, I don't know how to do time analyzation and power analyzation. Signal15.mat is the file

Oh, i am just testing it, but i don't know what type of modulation it could be. I wonder, if it is not FM, but i could be PSK too.

If you want to have a starting point, following code basically takes the psd of the signal, so that you will be able to obtain the frequency characteristics of your signal:
Fs=10000;%sampling frequency of your signal
After this, you can apply the necessary filter or do any kind of operation based on your need.
