GOPPA CODES FROMARTIN-SCHREIER FUNCTION FIELDS
Han Wang · Chinese Annals of Mathematics · 1994
A class of Goppa codes is constructed by using Artin-Schreier function fields, of which thenumber of prime divisors of degree olle is obtained for some cases, and their minimum distance,duallty and selfeduality are discussed. At laSt the sublield subcode of Artin-Schreier code isinvestigated, the true dimension under certain conditions is given and the covering radius andminimum distance are estimated.
