This paper describes scale-recursive symbol constellations for the synchronous multiple-access (MA) channel, which can be seen as a generalization of Voronoi coding. The constellations are related by a fixed scaling and rotation, and are designed so that in the noise-free case, the combined signal always falls onto an appropriate lattice. This allows high throughput and a linear complexity decoding algorithm. Novel constellations of up to 24 dimensions are given that show improved performance over conventional rectangular lattices.
