%0 Journal Article %T An Approximate Coding-Rate Versus Minimum Distance Formula for Binary Codes %A Yosef Akhtman %A Robert G. Maunder %A Lajos Hanzo %J Mathematics %D 2012 %I arXiv %X We devise an analytically simple as well as invertible approximate expression, which describes the relation between the minimum distance of a binary code and the corresponding maximum attainable code-rate. For example, for a rate-(1/4), length-256 binary code the best known bounds limit the attainable minimum distance to 65
