Abstract

We present a list decoding algorithm for quaternary negacyclic codes over the Lee metric. To achieve this result, we use a Sudan-Guruswami type list decoding algorithm for Reed-Solomon codes over certain ring alphabets. Our decoding strategy for negacyclic codes over the ring Z4\mathbb Z_4 combines the list decoding algorithm by Wu with the Gr\"obner basis approach for solving a key equation due to Byrne and Fitzpatrick.
