New class of t-error correcting and all unidirectional error detecting (t-EC/AUED) codes

摘要

A new class of t-error correcting and all unidirectional error detecting (t-EC/AUED) codes with reduced number of check bits is presented. The encoding/decoding algorithms for this class of codes can be implemented with faster as well as simpler hardware. The ROM implementation of the proposed scheme results in significant saving of word length.
