Abstract
Data rate requirements for cellular communications are expected to increase 1000–fold by 2020, compared to 2010. This is mainly because of the rapid increase in the number of wireless devices and data hungry applications per–device. This creates a formidable bandwidth crisis. Milimeter–wave (mmWave) systems with massive multiple–input multiple–output (MIMO) operation are two complementary concepts poised to meet this exploding demand, as verified by the wealth of investigations by both industry and academia. Nevertheless, existing MIMO processing techniques, requiring a dedicated radio–frequency (RF) up/down–conversion chain per antenna, results in prohibitively high complexity and cost of the mmWave prototypes.

Data rate requirements for cellular communications are expected to increase 1000–fold by 2020, compared to 2010. This is mainly because of the rapid increase in the number of wireless devices and data hungry applications per–device. This creates a formidable bandwidth crisis. Milimeter–wave (mmWave) systems with massive multiple–input multiple–output (MIMO) operation are two complementary concepts poised to meet this exploding demand, as verified by the wealth of investigations by both industry and academia. Nevertheless, existing MIMO processing techniques, requiring a dedicated radio–frequency (RF) up/down–conversion chain per antenna, results in prohibitively high complexity and cost of the mmWave prototypes. The primary objective of this paper is to present a complete feasibility study on alternative beamforming techniques targeted to reduce the system complexity without drastically compromising its performance. More precisely, at 28 GHz, we investigate the end–to–end performance of two different lens–based beamforming topologies. Our study is an amalgam of theoretical modelling, electromagnetic design, and prototype manufacturing, yielding a comprehensive mmWave, massive MIMO performance evaluation. (Less)
