摘　　要：以高阶统计量数学分析方法,对混合高斯模型进行研究,并给出理论计算结果。重点讨论二元混合高斯模型,给出高阶统计量的理论值,用Matlab仿真不同方差和不同均值时多膜性、对称性和斜度值、峰度值的估计结果,并比较斜度值、峰度值的理论结果和仿真结果,验证理论结果的正确性,为通信理论中混合高斯模型的研究做补充。The higher- order statistic of Gaussian mixture model is analyzed, in addition, the accurate results are demonstrated. Especially,Gaussian mixture models of two components are discussed,the analyzing of properties of multimodel and symmetry and the results of properties of skewness and kurtosis under homoscedastic and heteroscedastic conditions are simulated by Matlab,and then the Matlab simulative results indicate that they are of universal sense and right compare to theoretical results.
