For any Hadamard matrices Hn of order n, we give a method to define a doubly even self-dual [2n, n] code C(NHn). Then we will prove that two Hadamard equivalent matrices define equivalent codes.Previous article in issueNext article in issueRecommended articlesCited by (0)Copyright © 1987 Published by Elsevier Inc.
