Fronthaul-Aware Group Sparse Precoding and Signal Splitting in SWIPT C-RAN
Yanjie Dong, Md. Jahangir Hossain, Julian Cheng +1
We investigate the precoding, remote radio head (RRH) selection and signal splitting in the simultaneous wireless information and power transferring (SWIPT) cloud radio access netw…
Downlink Energy Efficiency of Power Allocation and Wireless Backhaul Bandwidth Allocation in Heterogeneous Small Cell Networks
Haijun Zhang, Hao Liu, Julian Cheng +1
The widespread application of wireless services and dense devices access have triggered huge energy consumption. Because of the environmental and financial considerations, energy-e…
Distributed Join-the-Idle-Queue for Low Latency Cloud Services
Chunpu Wang, Chen Feng, Julian Cheng
Low latency is highly desirable for cloud services. To achieve low response time, stringent timing requirements are needed for task scheduling in a large-scale server farm spanning…
Dynamic Cross-Layer Beamforming in Hybrid Powered Communication Systems With Harvest-Use-Trade Strategy
Yanjie Dong, Md. Jahangir Hossain, Julian Cheng +1
The application of renewable energy is a promising solution to realize the Green Communications. However, if the cellular systems are solely powered by the renewable energy, the we…
Secure Beamforming in Full-Duplex SWIPT Systems
Yanjie Dong, Ahmed El Shafie, Md. Jahangir Hossain +3
Physical layer security is a key issue in the full duplex (FD) communication systems due to the broadcast nature of wireless channels. In this paper, the joint design of informatio…
A New Asymptotic Analysis Technique for Diversity Receptions Over Correlated Lognormal Fading Channels
Bingcheng Zhu, Julian Cheng, Jun Yan +3
Prior asymptotic performance analyses are based on the series expansion of the moment-generating function (MGF) or the probability density function (PDF) of channel coefficients. H…
