The Resaearch on the Minimum Distance of Generalized Hadamard Codes

摘要

The problem about the minimum distance of generalized Hadamard code C is discussed. This paper derived that the generalized Hadamard code C was a code in F2n, the length of the code was n, and the dimension was 2(n+1). Moreover, the minimum distance of generalized Hadamard codes is (n-3)/2, which is proved finally.
