하이브리드 프리코딩(HP) 기술은 밀리미터파 통신 시스템을 위한 유망한 접근 방식으로 널리 간주되어 왔습니다. 일반적으로 복잡한 고해상도 위상 천이기 네트워크를 갖춘 기존 HP 구조는 최적에 가까운 스펙트럼 효율을 달성할 수 있지만 에너지 소비가 높습니다. 에너지 효율적인 스위치 네트워크를 갖춘 HP 아키텍처는 에너지 소비를 크게 줄일 수 있습니다. 최대 에너지 효율성을 달성하기 위해 이 문서에서는 스위치 네트워크를 갖춘 HP 아키텍처에 중점을 두고 잠재적인 어레이 이득을 제공할 수 있는 mmWave MIMO 시스템을 위한 새로운 적응형 아날로그 네트워크 HP 구조를 고려합니다. 또한, 이 새로운 구조의 HP 설계 문제를 위해 다중 사용자 적응형 좌표 업데이트 알고리즘이 제안되었습니다. 시뮬레이션 결과는 우리가 제안한 설계가 사용자 수가 적을 때 최근 제안된 다른 HP 방식보다 더 나은 에너지 효율성을 달성할 수 있음을 검증합니다.

Abstract: The hybrid precoding (HP) technique has been widely considered as a promising approach for millimeter wave communication systems. In general, the existing HP structure with a complicated high-resolution phase shifter network can achieve near-optimal spectral efficiency, however, it involves high energy consumption. The HP architecture with an energy-efficient switch network can significantly reduce the energy consumption. To achieve maximum energy efficiency, this paper focuses on the HP architecture with switch network and considers a novel adaptive analog network HP structure for such mmWave MIMO systems, which can provide potential array gains. Moreover, a multiuser adaptive coordinate update algorithm is proposed for the HP design problem of this new structure. Simulation results verify that our proposed design can achieve better energy efficiency than other recently proposed HP schemes when the number of users is small.

AB - The hybrid precoding (HP) technique has been widely considered as a promising approach for millimeter wave communication systems. In general, the existing HP structure with a complicated high-resolution phase shifter network can achieve near-optimal spectral efficiency, however, it involves high energy consumption. The HP architecture with an energy-efficient switch network can significantly reduce the energy consumption. To achieve maximum energy efficiency, this paper focuses on the HP architecture with switch network and considers a novel adaptive analog network HP structure for such mmWave MIMO systems, which can provide potential array gains. Moreover, a multiuser adaptive coordinate update algorithm is proposed for the HP design problem of this new structure. Simulation results verify that our proposed design can achieve better energy efficiency than other recently proposed HP schemes when the number of users is small.
