摘要：
A global procedure for recognition of analogue and digital modulation types, utilising the decision-theoretic approach, is developed. It involves two main steps: a reliable classification of the signal according to its amplitude and phase information contents; and a classification of the signal according to the modulation type. Computer simulations for different types of bandlimited modulated signals corrupted with bandlimited Gaussian noise sequence have been carried out. It is found that the threshold SNR for correct signal classification is about 10dB.
