摘要：
This paper considers a beamforming (BF) system for 60 GHz wireless communications. A low complexity codebook-based BF scheme that uses the signal angle-of-arrival (AOA) is proposed. This exploits the ability of a millimeter-wave (MMW) antenna array to provide the signal AOA. The effective power beam width (EPBW) is defined to obtain beams that are approximately orthogonal. A reduced transmit beam subset is generated using the AOA and EPBW. Training signals are used to find the best beam pair for communications. This leads to a significant reduction in BF setup time. Numerical results are presented which show that this low complexity solution can provide a BF gain approaching the theoretical maximum.
