Abstract

A key step in the design of a lattice code is the design of an n-dimensional constellation. Having selected a suitable lattice, the designer must choose a finite subset of points, perhaps with some translation or rotation, to define a set of codewords with the required properties. This paper outlines techniques for designing rotationally invariant codes using Leech and Sloane (1971) constructions A and B, presented in their paper. These lattices are either optimally dense or offer a good performance/complexity tradeoff in up to 32 dimensions. Their simplicity relative to other lattice constructions makes them worthy of considerations in higher dimensions.
