Abstract:
In this correspondence, we show that the problem of designing efficient
multiple-antenna signal constellations for fading channels can be
related to the problem of finding packings with large minimum distance
in the complex Grassmannian space. We describe a numerical optimization
procedure for finding good packings in the complex Grassmannian space
and report the best signal constellations found by this procedure. These
constellations improve significantly upon previously known results.
