Abstract
In this paper we consider perfect codes over two dimensional QAM-type constellations of any cardinal. Such constellations are going to be modeled by L-graphs, which are the two-dimensional family of multidimensional circulants, defined in [3]. We show that Gaussian graphs, Lee graphs and the Kronecker product of two cycles are included in this family. Therefore, our method to obtain perfect codes over these lattice subsets is a generalization of the techniques for searching perfect two-dimensional Lee codes and perfect codes over the Kronecker products of two cycles. In addition, we introduce some previously unreported perfect codes.
