| 摘 要： | 用四阶累积量构造了一个较通用的累积量矩阵，该矩阵符合ＭＵ－ＳＩＣ算法的结构，从而可进行波达方向（ＤＯＡ）估计。由于四阶累积量对高斯噪声和干扰不敏感，从而可提高估计的分辨性能。当完全使用这个矩阵，可估计比经典ＭＵＳＩＣ法更多的源信号的参数。

| Abstract: | This paper gives a general fourth order cumulant matrix which conforms with the structure of MUSIC algorithm.Therefore we can estimate the direction of arrival (DOA).Because the fourth order cumulant is insensitive to Gaussian noise or interference,the performance of the estimates can be increased.When we use the matrix to form an algorithm,it can estimate more sources than classical MUSIC algorithm. |
