摘要：

Let F-q be a finite field of cardinality q, where q is a power of a prime number p, n a positive multiple of p, l a prime number and F-ql an extension field of F-q with degree l. First, the structure and a canonical form decomposition of any cyclic F-q-linear code over F-ql of length n are presented. Then from this decomposition and by the theory of linear codes over finite chain rings, enumeration, construction and encoder of these codes are investigated. Furthermore, the dual code of any cyclic F-q-linear code over F-ql of length n is studied. (C) 2014 Elsevier Inc. All rights reserved.
