摘要 介绍了一种基于高阶累积量的数字调制信号识别算法,利用从信号的二阶、四阶和六阶累积量中提取的3个特征参数实现多种常用数字调制信号的识别,可以很好地抑制高斯白噪声,且允许有相位偏差,能够在较低信噪比下实现对2ASK/BPSK、4ASK、QPSK、2FSK、4FSK、8FSK、16QAM等多种信号的分类。经理论推导和仿真实验,证实了该方法的有效性。 This paper introduces an algorithm of digital modulation signals recognition based on higher-order cumulants. This method can classify many digital signals using three feature parameters which are picked up from two-order, four-order and six-order cumulants, and suppress white Gaussian noise. It can allow for phase deflection, and identify digital modulation signals: 2ASK/BPSK, 4ASK,QPSK,2FSK,4FSK,8FSK,16QAM under small SNR. The theoretical arguments and simulation experiments verify this method's validity.
