| 摘 要： | 调制方式的识别对于通信信号分析有着重要的作用。在现有有关调制识别的研究中，大部分都考虑的是加性高斯白噪声理想信道（AWGN）。文中通过仿真分析A．K．Nandi和E．E．Azzouz提出的数字调制识别算法（DMRAs）在衰落信道中的性能，详细研究了衰落信道特性对调制识别的影响。最后，得出了一些具有规律性的结论，对进一步深入研究衰落信道中调制识别技术具有一定的指导意义。

| Abstract: | Modulation recognition has significant influences on the analysis of communication signals. Most of existing research papers about this subject assumes the AWGN ideal channel. In this paper, we simulate the digital modulation recognition algorithms （DMRAs） presented by A.K.Nandi and E.E.Azzouz and analyze the performance of the algorithm on fading channels, and then we give emphasis to the influence of fading channel characteristics on modulation recognition. Finally we get some general rules, which make sense for further research on modulation recognition techniques for fading channels. |
