Abstract :
We present a method for decoding an arbitrary linear code over a Galois ring ℛ by a process of lifting decoding algorithms for a family of linear codes over a finite field 𝒦 forming an α-element chain, where 𝒦 is the quotient field of ℛ and ℛ has characteristic pα. As a new result, this method also works for linear codes over ℛ which are nonfree ℛ-modules
