Abstract: Two methods of the classification of digital modulations ASK, FSK2, FSK4, MSK, BPSK, QPSK, 8PSK and QAM-16 are presented. The first algorithm is based on module and phase spectrogram analysis. Here it is very important to estimate the symbol length of the received signal and thus we introduce two methods for this purpose. They are based on the wavelet transform and cepstrum analysis. The second algorithm of modulation classification uses instantaneous values of signal (instantaneous amplitude, phase and frequency). A method of the practical verification of classification algorithms in laboratory environment is described.
