一种工程化的数字调相信号快速分类识别方法

在数字调制分类中,信号的相位周期特性会形成相位的卷叠并降低对接收到的射频信号的自动数字调制正确分类的概率。根据多进制数字相位调制(multiple-level phase shift keying,MPSK)信号的相位特征,通过相位去卷叠、根据最小均方误差原则去线性相位分量,以及相位的模π运算,提出了一种MPSK信号的分类方法。实验结果表明,基于相位特征的通信信号的自动调制分类算法具有很强的鲁棒性,对不同类型和滚降系数的脉冲成形滤波器和高码元速率都达到了较高的识别率。

A practical fast digital phase modulation signal classification and recognition method

Classification of digital modulation,the signal characteristics of the phase of the cycle will cause the phase volume and reduce overlapping signals in the received RF digital modulation automatically correct classification probability.According to the principle of minimum mean square,a phase modulation and phase modulation signal classification features as well as 2PSK and MPSK classification.Experimental results show that this phase characteristics of communication signals based on the automatic modulatio...
