Abstract
We consider the problem of preliminary classification of digitally modulated signals. The goal is to simplify further signal analysis (synchronization, signal separation, modulation identification and parameters estimation) by making initial separation among the most known classes of signals. Proposed methodology is mainly based on Higher Order Statistics (HOS) of the distributions of instantaneous amplitude and frequency. The experimental results emphasize the performance of the proposed set of features.
