Description In this paper, we generalize the Hadamard transform to the the case of lapped transform A matrix A(z) is a lapped Hadamard transform if it satisfies A ~ ( ~- ' ) A ( ~ ) = a ~ for some integer a and all the entries of its coefficient matrices are i1. Many meth-ods have been proposed to construct lapped Hadamard matrices. In this paper, we will study these matrices using the theory of pa-raunitary filter bank. This approach not only greatly simplifies the analysis of lapped Hadamard transform but also gives rise to new construction methods that can generate a much wider class of lapped Hadamard matrices. 1.
