On binary codes related to mutually quasi-unbiased weighing matrices

Abstract

Some mutually quasi-unbiased weighing matrices are constructed from binary codes satisfying certain conditions. Motivated by this, in this note, we study binary codes satisfying the conditions. The weight distributions of binary codes satisfying the conditions are determined. We also give a classification of binary codes of lengths $8,16$ and binary maximal codes of length $32$ satisfying the conditions. As an application, sets of $8$ mutually quasi-unbiased weighing matrices for parameters $(16,16,4,64)$ and $4$ mutually quasi-unbiased weighing matrices for parameters $(32,32,4,256)$ are constructed for the first time.
