| 摘 要： | 针对多径信道中MPSK信号的调制分类问题，提出一种新的基于高阶累量的分类算法，算法所用特征对平坦衰落信道具有衰落不变性，对频率选择性衰落信道也具有很强的抗多径能力。与已有方法相比，本文算法极大地降低了对多径信道冲激响应模式的限制，更具适应性。理论分析和计算机仿真试验都证明了新分类算法的稳健性和有效性。

| Abstract: | A new algorithm based on higher order cumulants is proposed for classification of MPSK signals in multipath channel environments. The feature used in the algorithm is invariant with respect to flat fading, and can resist multipath fading of frequency-selecting channel in quite a few degree. Compared with other existing algorithms, the proposed algorithm relaxes restrictions on the model of channel response, therefore be of more generality. Theoretical analysis and computer simulation justify the robusticity and the efficiency of the new classification algorithm. |
