Idempotents and the BCH bound

Abstract

Using a characterization of the idempotents of a narrow-sense primitive binary BCH code, the authors are able to give classes of such codes whose minimum distance does not exceed the BCH bound. Their results are compiled in a table.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
