摘要
The existence is shown of a set of (pm - 1) generalized Hadamard matrices H(p, p2m) of order p2m, each of which is symmetric and regular. When normalized to become unitary matrices, they form a multiplicative group of order pm, simply isomorphic to the additive group of GF(pm). The rows of these (pm - 1) matrices are shown to be the image, under the well-known isomorphic mapping relating the pth roots of unity to the elements of GF(p), of the set of vectors of a given weight in the tri-weight extended-BCH code of length p2m, dimension 3m + 1, and minimum weight (p - 1)p2m-1 - pm-1. © 1969 Academic Press, Inc.
