An Efficient, PSP-Based Digital Modulation Classifier

This paper presents several methods that can be used for the design of an efficient, PSP-based digital modulation classifier. Such methods include: (a) an efficient Decision-Making Procedure that reaches a final decision in stages, (b) a reduced-complexity Feature-Generation Algorithm that generates the necessary discriminating metrics, (c) a method to calculate approximate thresholds that uses polynomial fitting techniques to establish a functional relationship between the threshold and the Signal-to-Noise Ratio. Selected performance simulation results presented herein demonstrate the validity of these methods for digital, memoryless modulation menus.
