Primitive Idempotents and Weight Distributions of Irreducible Cyclic Codes of Length 5l^m
Abstract
Abstract
Let be a finite field with q elements such that and gcd = 1, where is a prime. In this paper, we give all primitive idempotents in a ring [x] . We give the weight distributions of all irreducible cyclic codes of length over .
Keywords: Primitive Idempotents, Cyclotomic Cosets, Cyclic Codes.
