摘要 提出了一种以调制信号的高阶累积量为分类特征向量,支持向量机为分类器的数字调制方式自动识别算法,对4ASK、BPSK、QPSK、2FSK、4FSK、MSK、16QAM等卫星通信常用调制信号进行调制方式的自动识别,仿真结果表明,此算法简便,在卫星高斯白噪声信道(AWGN)较低信噪比环境下仍然有较高的识别率. 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.
