| 摘 要： | 提出了一种新的基于Ｈａｄａｍａｒｄ变换的相关辨识方法。该方法用Ｍ序列作为辨识信号，用Ｍ矩阵与Ｈａｄａｍａｒｄ矩阵的相似关系，并通过Ｈａｄａｍａｒｄ变换计算系统的单位冲激响应。根据Ｇａｌｏｉｓ域理论，得到求相似变换阵的算法。文中还给出了部分仿真结果。

| Abstract: | In this paper, a Hadamard transform based on the correlation analysis identification method is presented. This method exploits the similarity between M matrix and the hadamard matrix to compute the unit impulse responses of systems by performing the Hadamard transform. We establish an algorithm for determining the matrices of the similar transformation using the theory of Galois fields. At the end of the paper, some simulation results are given. |
