dc.description.abstractIn this work, we provide a geometrical framework for the analysis and design of beamformer codebooks with finite number of beamformer vectors. We present a design criterion for good beamfomer codebooks and show the equivalence of the beamformer design problem to two other known problems. First, the beamformer design problem can be directly posed as a problem of packing <b><i>2</i></b> dimensional subspaces in a <b><i>2t</i></b> dimensional Grassmannian manifold, <b><i>t</i></b> being the number of transmit antennas. And second, under certain conditions, the beamformer design problem is equivalent to the construction of unitary space time constellations.en_US
