Curves on torus layers and coding for continuous alphabet sources
Antonio C. de A. Campello, Cristiano Torezzan, Sueli I. R. Costa · 2012
In this paper we consider the problem of transmitting a continuous alphabet discrete-time source over an AWGN channel. The design of good curves for this purpose relies on geometrical properties of spherical codes and projections of N-dimensional lattices. We propose a constructive scheme based on a set of curves on the surface of a 2N-dimensional sphere and present comparisons with some previous works.
