Abstract :
A common method for constructing t-error correcting/all unidirectional error detecting (t-EC/AUED) codes is to append a tail to the t-EC code where the tail is a function of the weight of the codeword. We present a method to reduce the weight distribution of the t-EC codes by using a DCm(k+d,k) code and the method of Bruck and Blaum (1992) simultaneously. It is shown that our t-EC/AUED codes have the better information rates than the previously developed codes due to the smaller tails
