A note on SEC/AUED codes. A common method of constructing single error correcting/all unidirectional error detecting (SEC/AUED) codes is to choose a SEC code and then to append a tail such that the new code can detect all unidirectional errors. The tail is a function of the weight of the codeword. We present a technique to reduce the weight distribution of the SEC code so that the tail needed is smaller. We also present a new method to construct the tail.
