A new class of t-error correcting/d-error detecting (d>t) and all unidirectional error detecting codes

In this paper, a new class of t-error correcting/d-error detecting and all unidirectional error detecting (t-EC/d-ED/AUED) codes has been proposed. Compared to the published results, this scheme, in general, needs less or equal number of check bits. Further, both the encoding/decoding algorithms for this class of codes can be implemented with faster and simpler hardware. In case of ROM implementation, the proposed scheme results in significant saving in word length.
