Emerging from our general geometric theory for detection problems is the geometric structure of the space of probability measures. On this non-Riemannian manifold, distance cannot be defined, making it impossible to construct directly signal constellations for non-Gaussian detection problems. As the number of observations increases, an approximate structure for signal constellations can be obtained. We show that square-wave signals play a prominent role in non-Gaussian detection problems. A procedure for determining optimum signal sets is described. Optimum signal constellations depend on signal-to-noise ratio, in some cares changing their geometric form as signal-to-noise ratio changes
