Robust Adaptive Beam Tracking for Mobile Millimetre Wave Communications
Chunshan Liu, Min Li, Lou Zhao +4
Millimetre wave (mmWave) beam tracking is a challenging task because tracking algorithms are required to provide consistent high accuracy with low probability of loss of track and…
Millimeter-Wave Beam Search with Iterative Deactivation and Beam Shifting
Chunshan Liu, Min Li, Lou Zhao +3
Millimeter Wave (mmWave) communications rely on highly directional beams to combat severe propagation loss. In this paper, an adaptive beam search algorithm based on spatial scanni…
A Distributed Multi-RF Chain Hybrid mmWave Scheme for Small-cell Systems
Lou Zhao, Jiajia Guo, Zhiqiang Wei +2
This paper proposes a distributed hybrid millimeter wave (mmWave) scheme to exploit the structure of a Densely Deployed Distributed (DDD) small-cell-base-stations (SBSs) system for…
Millimeter Wave Systems for Wireless Cellular Communications
Lou Zhao
This thesis considers channel estimation and multiuser (MU) data transmission for massive MIMO systems with fully digital/hybrid structures in mmWave channels. It contains three ma…
Multi-Beam NOMA for Hybrid mmWave Systems
Zhiqiang Wei, Lou Zhao, Jiajia Guo +2
In this paper, we propose a multi-beam non-orthogonal multiple access (NOMA) scheme for hybrid millimeter wave (mmWave) systems and study its resource allocation. A beam splitting…
Multi-cell Hybrid Millimeter Wave Systems: Pilot Contamination and Interference Mitigation
Lou Zhao, Zhiqiang Wei, Derrick Wing Kwan Ng +2
In this paper, we investigate the system performance of a multi-cell multi-user (MU) hybrid millimeter wave (mmWave) communications in a multiple-input multiple-output (MIMO) netwo…
