Abstract

A modification and efficient implementation of the SKHNE (Sugiyama, Kasahara, Hirasawa, Namekawa, Euclid) algorithm for a class of BCH codes is proposed. Envisaged as part of an adaptive data protection (ADP) software application it is designed to operate (decode and error correct) for binary "narrowsense" BCH(8,t) codes providing increasing level of protection against error in accordance with user choices. While such codes cause loss of compression the improvement in error probability is dramatic, e.g. from 10 1-55 to 10-41 approximately for BCH(8,10), with a 42% loss of compression. It may function in applications requiring a supplemental inner code or a stand alone data protection shield.
