Abstract(in English) | This paper proposes optimal beam patterns of analog beamforming for SU (Single User) massive MIMO (Multi-Input Multi-Output) transmission systems. In conventional hybrid beamforming, rectangular patch array antennas implemented on a planar surface with linear phase shift beam patterns have been used widely. However, it has not been clear yet, whether the such configuration of design items is optimal or not. Therefore, we propose a method using OBPB (Optimal Beam Projection Beamforming) for designing configuration parameters of the hybrid beamforming, such as beam patterns, the number of beams (streams), a shape of array antennas, and so on. By using the method, the optimal beam patterns are derived first, and are projected on the assumed surface to calculate the achievable number of streams and resulting channel capacity. |
