Criterion for Distinguishing Between the FSK and PSK Signals

We consider the problem of determining the type of modulation of radio signals with the a priori unknown parameters. A new criterion for distinguishing between the frequency-shift keyed and phase-shift keyed signals is proposed. Replacing the conventional criterion by the proposed one allows one to...

Zusammenfassung:	We consider the problem of determining the type of modulation of radio signals with the a priori unknown parameters. A new criterion for distinguishing between the frequency-shift keyed and phase-shift keyed signals is proposed. Replacing the conventional criterion by the proposed one allows one to improve the interference immunity of many existing algorithms for determining the modulation type.
