Hybrid Analog-Digital Beamforming for Multiuser MIMO Millimeter Wave Relay Systems
Xuan Xue, Tadilo Endeshaw Bogale, Xianbin Wang +2
This paper proposed new hybrid, analog-digital, beamforming for a multiuser millimeter wave (mm-wave) relay system. For this system, we consider a sum rate maximization problem. Th…

Tadilo Endeshaw Bogale, Long Bao Le
There have been active research activities worldwide in developing the next-generation 5G wireless network. The 5G network is expected to support significantly large amount of mobi…
Hybrid Analog-Digital Channel Estimation and Beamforming: Training-Throughput Tradeoff
Tadilo Endeshaw Bogale, Long Bao, Xianbin Wang
This paper designs hybrid analog-digital channel estimation and beamforming techniques for multiuser massive multiple input multiple output (MIMO) systems with limited number of ra…
Pilot Contamination Mitigation for Wideband Massive MMO: Number of Cells Vs Multipath
Tadilo Endeshaw Bogale, Long Bao Le, Xianbin Wang +1
This paper proposes novel joint channel estimation and beamforming approach for multicell wideband massive multiple input multiple output (MIMO) systems. Using our channel estimati…
