Abstract: The All Unidirectional Error Detection (AUED) codes are among the ways of guarding against erroneous correction and a t-Error Correction (EC)/All Unidirectional Error Detection (AUED) code can be constructed by appending a single check symbol (P) to a linear t-EC code to achieve the AUED property. Whenever, a t-EC/AUED code is used to encode information in a transmission side such information need to be decoded at the receiving side. Methods and techniques proposed in literature for constructing t-EC/AUED codes are either come with no Decoding algorithm or if a decoding a algorithm is proposed, it lacks the mathematical proof. This study adopts a decoding algorithm from the literature and derives a mathematical proof for it. Simulation software is also developed and results for the encoding and decoding processes of four different encoding methods are presented. Based on the mathematical proof and the simulation results obtained, this study claims that the adopted algorithm is a Universal Decoding algorithm.
