摘要
调制样式识别和调制参数估计是电子对抗中的一个重要环节,也是信号分析的一个快速发展的领域。本文主要分析了模拟调幅AM和数字调幅2ASK及4ASK信号,然后提取了能有效区分它们的特征参数,用MATLAB软件完成了仿真实验。实验证明本文提取的特征参数是非常有效的。
Modulation recognition and parameter estimation is an important field in electronic countermeasures,it also is a rapidly evolving field of signal analysis. This paper studies the sings of AM, 2ASK and 4ASK,some effective parameters are be found to distinguish them. Some simulation are finished in MATLAB, simulation shows the parameters are very effective.
