Annotations languages:

The results of cumulants set optimization for recognition of phase constellations shape of linear digital modulation signals are given in the article. Optimization is carried out by research of probabilistic characteristic of phase constellation type recognition method based on the cumulant analysis of signals, in accordance with the heuristic method of exhaustive search and statistical tests Monte Carlo method. The optimal sets of cumulants for providing of the established efficiency indexes of the modulation type recognition system and statistical probabilities of correct recognition are got.
Keywords: modulation recognition, cumulant analysis, linear digital modulation, optimization, phase constellation
