Constant weight codes: An approach based on Knuth's balancing method
Vitaly Skachek, Kees A. Schouhamer Immink · 2011
In this article, we study properties and algorithms for constructing sets of `constant weight' codewords with bipolar symbols, where the sum of the symbols is a constant q, q ≠ 0. We show various code constructions that extend Knuth's balancing vector scheme, q = 0, to the case where q >; 0. We compute the redundancy of the new coding methods.
