Demo : Millimeter-Wave Massive MIMO Testbed with Hybrid Beamforming
(2020) 2020 IEEE Wireless Communications and Networking Conference Workshops, WCNCW 2020 In 2020 IEEE Wireless Communications and Networking Conference Workshops, WCNCW 2020 - Proceedings- Abstract
Massive multiple-input multiple-out (MIMO) is vital in millimeter-wave (mmWave) bands to obtain large array gains. However, there are practical challenges, such as high hardware cost and power consumption in such systems. A promising solution to these problems is to adopt a hybrid beamforming architecture. This architecture has a much lower number of transceiver (TRx) chains than the total antenna number, resulting in cost- and energy- efficient systems. In this demo, we present a real- time mmWave (28GHz) massive MIMO testbed with hybrid beamforming. This testbed has a 64- antenna/16-TRx unit for beam-selection, which can be expanded to larger array sizes in a modular way. For testing everything from baseband processing algorithms to... (More)

This testbed has a 64- antenna/16-TRx unit for beam-selection, which can be expanded to larger array sizes in a modular way. For testing everything from baseband processing algorithms to scheduling and beam-selection in real propagation environment, we extend the capability of an existing 100-antenna/100-TRx massive MIMO testbed (below 6GHz), built upon software-defined radio technology, to a flexible mmWave massive MIMO system.
