Hybrid Beamforming for millimetre Wave massive MIMO Communication: A Survey

Abstract

Hybrid Beamforming Massive MIMO Systems for millimetre Waves are seen as fundamental
technologies to meet continuously increasing demand of data traffic in near future with seamless
connectivity and service quality. For millimetre waves communication the conventional fully digital
beamforming techniques become impractical as they demand for high power, cost and complexity.
The hybrid beamforming architecture minimizes the hardware cost, complexity, power consumption
with nearly optimal performance which is the need of future generation equipment’s. Therefore,
hybrid beamforming received significant attention form research community specifically for 5th
generation wireless networks. This paper provides insights offundamental keypoints, hybrid
beamforming structure, associated challenges anddetailed survey ofprominent research work with
respect to analog beamforming metrics, digital beamforming metrics and spectral efficiency as
performance parameter.
