Set partitioning of Gaussian integer constellations and its application to two-dimensional interleaving

Codes over Gaussian integers have been proposed for coding over two-dimensional (2D) signal spaces, for example, using quadrature amplitude modulation. Here, it is demonstrated that the concept of set partitioning can be applied to Gaussian integer constellations that are isomorphic to 2D modules ov...
