Method of modulation recognition of typical communication satellite signals based on cyclostationary

The recognition of communication satellite signals” modulation types is indispensable in so many applications., especially in satellite communication field and is an important aspect of the category in pattern recognition. This paper demonstrates the cyclostationary method is appropriate for modulation recognition. With the advantages of better anti-noise property., containing more information and revealing the nature of the cyclostationary signal. In this paper., some new characteristic parameters are advanced and verified by simulation.
