Gaussian Mixture Models-based Recognition of Digital Modulations of Noisy Signals

Original language description

A novel approach to the recognition of digital modulations is presented. It is based on features that characterize a specific kind of modulation or a group of modulations. These features are calculated from the instantaneous amplitude, instantaneous phase, and spectrum symmetry of the unknown signal. To recognize the modulations, an analysis of the features is carried out by means of a classifier based on Gaussian mixture models. The method was designed for 2ASK, 2FSK, MSK, BPSK, QPSK, and 16QAM modulations. They belong to the widely used digital modulations in recent communication systems. Simulation results demonstrating performance of the method are presented. The testing signals are corrupted by white Gaussian noise.
