Multi-Carrier Modulation: An Evolution from Time-Frequency Domain to Delay-Doppler Domain
Hai Lin, Jinhong Yuan, Wei Yu +2
The recently proposed orthogonal delay-Doppler division multiplexing (ODDM) modulation, which is a delay-Doppler (DD) domain multi-carrier (DDMC) modulation scheme based on the DD…
Massively Distributed Antenna Systems with Non-Ideal Optical Fiber Front-hauls: A Promising Technology for 6G Wireless Communication Systems
Lisu Yu, Jingxian Wu, Andong Zhou +2
Employing massively distributed antennas brings radio access points (RAPs) closer to users, thus enables aggressive spectrum reuse that can bridge gaps between the scarce spectrum…
Max-Min Optimal Beamforming for Cell-Free Massive MIMO
Andong Zhou, Jingxian Wu, Erik G. Larsson +1
This letter develops an optimum beamforming method for downlink transmissions in cell-free massive multiple-input multiple-output (MIMO) systems, which employ a massive number of d…
Optimal Status Update for Age of Information Minimization with an Energy Harvesting Source
Xianwen Wu, Jing Yang, Jingxian Wu
In this paper, we consider a scenario where an energy harvesting sensor continuously monitors a system and sends time-stamped status updates to a destination. The destination keeps…
Queue-Aware Energy-Efficient Joint Remote Radio Head Activation and Beamforming in Cloud Radio Access Networks
Jian Li, Jingxian Wu, Mugen Peng +1
In this paper, we study the stochastic optimization of cloud radio access networks (C-RANs) by joint remote radio head (RRH) activation and beamforming in the downlink. Unlike most…
Quickest Change Detection with Mismatched Post-Change Models
Jingxian Wu, Jing Yang
In this paper, we study the quickest change detection with mismatched post-change models. A change point is the time instant at which the distribution of a random process changes.…
