System Energy-Efficient Hybrid Beamforming for mmWave Multi-user Systems
Vu Nguyen Ha, Duy H. N. Nguyen, Jean-Francois Frigon
This paper develops energy-efficient hybrid beamforming designs for mmWave multi-user systems where analog precoding is realized by switches and phase shifters such that radio freq…
Computation Offloading and Resource Allocation for Backhaul Limited Cooperative MEC Systems
Phuong-Duy Nguyen, Vu Nguyen Ha, Long Bao Le
In this paper, we jointly optimize computation offloading and resource allocation to minimize the weighted sum of energy consumption of all mobile users in a backhaul limited coope…
Joint Data compression and Computation offloading in Hierarchical Fog-Cloud Systems
Ti Ti Nguyen, Vu Nguyen Ha, Long Bao Le +1
Data compression has the potential to significantly improve the computation offloading performance in hierarchical fog-cloud systems. However, it remains unknown how to optimally d…
Radio resource management for high-speed wireless cellular networks
Vu N. Ha
The fifth-generation (5G) wireless cellular system, which would be deployed by 2020, is expected to deliver significantly higher capacity and better network performance compared to…
