Re: [Discuss-gnuradio] Detection and classification of signals

[Ben Hilburn]

Ben -

Searching for "Automatic Modulation Classification (AMC)", on Google or IEEExplore, will give you fairly good start =)

Related terms may be: "Peak Detection", "Robust Statistics", and even "Primary User Detection" (from the cognitive radio side of things).

Cheers,

Ben

Hi all,

I'm working an a little project using gnuradio for receiving ham radio
psk31 signals.  I can decode a signal given a rough estimate of the
carrier frequency but I'd really like to take a big swath of bandwidth
as the input, detect the psk31 signals, and decode them all in
parallel.

However I don't even know what search terms to use to find methods to
detect the peaks, and make a guess as to whether they are psk31.  What
words should I be typing into my google searches?

My naive first attempt would be to find the peaks in the intensity
that have about the correct width and then try to decode them, but I
thought there might be more robust techniques out there.

Cheers,
Ben
