Abstract

Classification of FSK/PSK signals is studied in accordance with the characteristics of hybrid modulation signals that have low interception probability. Attention is focused on the identification of FSK/PSK, PSK and FSK signals using binary trees. The amplitude and phase related characteristic statistics are sent to the classifier to achieve classification. Simulation results show that the method is effective. The correct classification rate of FSK/PSK hybrid modulation signal is no less than 99% at 5 dB SNR.

Key words： FSK/PSK hybrid modulation signal; modulation classification; phase shift keying (PSK); continuous phase frequency shift keying (CPFSK); discrete phase frequency shift keying (DPFSK)
