| 摘 要： | 自动调制识别是非协作通信系统接收机设计中的重要研究课题。本文针对模拟调制方式提出了一种基于决策理论的识别流程。在频域中分析了线性平滑的方法。提出了用Haar小波变换的方法对输入数据处理，提高在低信噪比时的识别效果。仿真结果表明。在低信噪比时，该流程有很高的识别正确率。

| Abstract: | Automatic modulation classification is an important research area for the receiver design in the non-cooperative communica- tion system. A analogue modulation classification flow based on the decision theoretic is proposed in this paper.We analysis the method of linear smoothing in the frequency domain.and present a method that adopts Haar wavelet transform to process the input data.The simulation result indicated that this flow a has a good classification rate in the low SNR environment. |
