     This paper presents a recognition method using high order cumulants and support vector machine(SVM). In the paper,seven kinds of digital modulation signals common used in satellite communication are discussed,including 4ASK,BPSK,QPSK,2FSK,4FSK,MSK and 16QAM. Computer simulations show that this algorithm is simple,efficient,and can work perfectly under a low SNR circumstance in satellite AWGN channel.
