Abstract

In this paper we investigate bounds on rate and minimum distance of codes with t availability. We present bounds on minimum distance of a code with t availability that are tighter than existing bounds. For bounds on rate of a code with t availability, we restrict ourselves to a sub-class of codes with t availability called codes with strict t availability and derive a tighter rate bound. Codes with strict t availability can be defined as the null space of an (m x n) parity-check matrix H, where each row has weight (r + 1) and each column has weight t, with intersection between support of any two rows at most one. We also present two general constructions for codes with t availability.
