In this paper, we investigate self-dual codes over finite rings, specifically the ring Z2m of integers modulo 2m. Type II codes over Z2m are introduced as self-dual codes with Euclidean weights which are a multiple of 2m+1. We describe a relationship between Type II codes and even unimodular lattices. This relationship provides much information on Type II… CONTINUE READING
