This paper presents a method for modulation recognition of digital signals using machine learning. This method first extracted seven characteristic parameters according to the instantaneous parameters and high-order cumulant characteristics of the signal, then combined the decision tree classifier, neural network classifier and support vector machine classifier in machine learning with these characteristic parameters, and finally realized the modulation recognition of MASK, MFSK, MPSK and MQAM signals. This method not only has low computational complexity and more recognized signals, but also improves the recognition rate at low SNR.
