摘要：
To solve the problems in modulation recognition of time-frequency overlapped two-signal in the single-channel, an algorithm based on cyclic cumulants used modulation recognition is presented Through computing the fourth-order cyclic cumulants of pretreated band signals, the feature vector for classification was extracted and then use the minimum-error criterion to classify time-frequency overlapped two-signal automaticly. Theoretical analysis and experiment results both verify that the algorithm is correct and efficient.
