Abstract :
This paper describes the design of beamformers when finite rate channel feedback is available in a multiple transmit antenna system. This paper also discusses a geometrical framework for the analysis and design criterion of beamformer codebooks construction with finite number of beam-former vectors to minimize the outage probability.
