How to make automatic signal Classification using either raw IQ data or after applying demodulation?

[Taqi99]

Hi all. I am trying to make automatic signal classifier. That is when we get a radio signal the program will determine what type of modulation scheme is being utilized (FM,AM,MSK,PSK,GMSK etc.). I have just started this project and any idea or link etc will be greatly appreciated. My own approach is to demodulate the iq data first by sending it to all type of demodulators then using voice detection to determine the valid modulation scheme.

Any type of help is appreciated.

I'd probably go for some sort of NN. But you'd need a large training set, and some good classifier criteria.

And of course google a lot (google automatically+detect+psk+qpsk😞
