본 논문에서는 SU(Single User) Massive MIMO(Multi-Input Multi-Output) 전송 시스템을 위한 최적의 아날로그 빔포밍 빔 패턴을 제안한다. SU Mass MIMO 시스템의 하이브리드 빔포밍에는 빔 패턴, 빔(스트림) 수, 배열 안테나 모양 등과 같은 여러 설계 매개변수가 있습니다. 기존 하이브리드 빔포밍에서는 선형 위상 천이 빔 패턴을 평면에 구현한 직사각형 패치 어레이 안테나가 널리 사용되어 왔다. 그러나 기존 구성이 최적인지 아닌지는 여전히 불분명합니다. 따라서 우리는 하이브리드 빔포밍의 구성 변수를 설계하기 위해 OBPB(Optimal Beam Projection Beamforming)를 이용하는 방법을 제안한다. 이 방법을 사용하면 최적의 빔 패턴이 먼저 도출되고 가정된 표면에 투영되어 달성 가능한 스트림 수와 결과적인 채널 용량을 계산합니다. 결과는 구형 표면을 가진 OBPB가 기존 구성보다 최소 3.5배 더 높은 채널 용량을 생성한다는 것을 나타냅니다.

Abstract: This paper proposes optimal beam patterns of analog beamforming for SU (Single User) massive MIMO (Multi-Input Multi-Output) transmission systems. For hybrid beamforming in SU massive MIMO systems, there are several design parameters such as beam patterns, the number of beams (streams), the shape of array antennas, and so on. 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 remains unclear whether existing configurations are optimal or not. Therefore, we propose a method using OBPB (Optimal Beam Projection Beamforming) for designing configuration parameters of the hybrid beamforming. 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 the resulting channel capacity. The results indicate OBPB with a spherical surface yields at least 3.5 times higher channel capacity than conventional configurations.
