Automatic Modulation Recognition of Satellite Communication Signal Based on Statistic Method


Automatic modulation recognition plays an important role in both civil and military applications. A new algorithm is proposed for recognition of some classic satellite communication signals, including ASK, FSK, PSK and QAM. Eight feature parameters are extracted from the statistic moments which show a virtue of good performance and low computation complexity. It is showed in simulation results that the average ratio of success recognition achieves 98% when SNR equals to 1 dB. Compared with algorithm in [4], this algorithm exhibits better performance and more practicability.
