New techniques for constructing EC/AUED codes

Two new techniques for constructing t-EC/AUED (error correcting/all unidirectional error detection) codes are presented. The first technique modifies the t-EC/AUED code in such a way that the weight distribution of the original code is reduced. So, a smaller tail is needed. Frequently, this technique gives less overall redundancy than the best available t-EC/AUED codes. The second technique improves the parameters of the tails with respect to previous results.<
