Self-dual Codes over Z_(p~m) and Construction of Unimodular Lattices
Zhixiang Yin · Communications technology · 2009
In this paper,the existent conditions of self-dual codes over Z_(p~m) are given,i.e.,when m is even,there exists self-dual code for all lengths over Z_(p~m);when m is odd,there exists self-dual code for even lengths over Z_(p~m).Moreover,a homomorphism map is defined,and the self-dual code over _(p~m) and inverse of the map is used to construct a unimodular lattice.
