We study spatial division multiple access in 60 GHz millimeter wave communications and focus on estimation of the optimal transmit beamforming vectors for stations and optimal receive beamforming vectors for the access point. An iterative antenna training protocol is developed, where the optimal transmit/ receive beamforming vectors are computed without explicit knowledge of the actual wireless channels...
We study antenna training method for millimeter wave MIMO communication systems and develop iterative antenna training (IAT) algorithm and protocols. The newly developed training method features low training overhead as well as low computation complexity, and has great application potential in practice.
