Abstract
In this paper, we design multiple-antenna signal constellations for a Rayleigh flat-fading channel unknown to the receiver. It is shown that good signal constellations correspond to packings with large minimum distances in complex Grassmannian space. We describe a numerical optimization procedure for finding such packings. The corresponding signal constellations improve significantly upon previously best-known signal constellations
