摘　　要：基于高阶累计量信号调制识别方法,采用添加高斯噪声来模拟信号带有的噪声。通过利用MATLAB软件进行仿真,从仿真结果得到,随着高斯噪声增加,达到较高的识别率,较好地呈现了信号识别变化的曲线图。In this paper,a modulation recognition method based on high-order cumulant signal is intro-duced.With MATLAB software,we made a simulation.The simulation results show that with the increase of Gaussian noise,a higher recognition rate can be obtained,which can be used to show the change of signal recog-nition curve.

关 键 词：调制识别 高斯噪声 高阶累计量
