A FAST ALGORITHM FOR MODIFIED HADAMARD TRANSFORM

He Yongfu;Liu Zhengping;Chen Tianyu  
On the basis of modified Hadamard transform,a fast algorithm for modied Hadamard transform is established in this paper. From special case of N=8,and by the method of the matrix decomposition,the principle and method of the fast modified Hadamard transform and its inversion transform are obtained. Subsequently the iteractive formula for general case are induced. The result shows that the algorithm is of high efficiency and fast speed.
