模拟信号调制方式识别

通信信号的调制识别是截获信号处理研究领域的一个重要课题，本文主要研究了基于调制信号时域瞬时信息的识别算法。在时域特征参数的提取部分，主要研究了A．K．Nandi等人提出的传统的特征参数，并针对利用传统特征参数进行调制识别的缺陷，提出了新的特征参数。在分类识别部分，采用决策理论实现了对模拟调制方式的识别。仿真结果表明，该流程有很高的识别正确率。

Recognition of Modulation System of Analogue Signals

The modulation identification of communication signals is an important subject in the research area of intercepted sig- nal processing. This paper mainly studies the recognition algorithm based on instantaneous information of modulation signal in time domain. In the extraction part of characteristic parameters in time domain, mainly researches the traditional feature parameters pro- posed by A.K. Nandi and others. And aiming at the defects of the modulation identification by using traditional characteristic parame- ters, the new feature parameters are proposed. In the part of classification recognition, the decision theory is adopted to realize the recognition of analog modulation mode. The simulation result indicates that this procedure has high classification recognition accuracy.
