Research on Modulation Recognition of the Communication Signal Based on Statistical Model

摘要

Modulation recognition is the key problems in noncooperative communication, communication detection and communication surveillance. Non-cooperate communication is commonly used in civilian and military applications, where it is required to monitor the activities of communication signals in space and intercept the signal information content with little prior knowledge. The paper describes the principium of the automatic modulation recognition of communicational signal based on statistical model, then analyses automatic modulation recognition of analog communicational signals and shows a method to achieve.
