Joint Spatial Division and Coaxial Multiplexing for Downlink Multi-User OAM Wireless Backhaul
Wen-Xuan Long, Rui Chen, Marco Moretti +2
Orbital angular momentum (OAM) at radio frequency (RF) provides a novel approach of multiplexing a set of orthogonal modes on the same frequency channel to achieve high spectral ef…
Access Points in the Air: Modeling and Optimization of Fixed-Wing UAV Network
Junyu Liu, Min Sheng, Ruiling Lyu +2
Fixed-wing unmanned aerial vehicles (UAVs) are of great potential to serve as aerial access points (APs) owing to better aerodynamic performance and longer flight endurance. Howeve…
Limitation of SDMA in Ultra-Dense Small Cell Networks
Junyu Liu, Min Sheng, Jiandong Li
Benefitting from multi-user gain brought by multi-antenna techniques, space division multiple access (SDMA) is capable of significantly enhancing spatial throughput (ST) in wireles…
MISO in Ultra-Dense Networks: Balancing the Tradeoff between User and System Performance
Junyu Liu, Min Sheng, Jiandong Li
With over-deployed network infrastructures, network densification is shown to hinder the improvement of user experience and system performance. In this paper, we adopt multi-antenn…
The Impact of Antenna Height Difference on the Performance of Downlink Cellular Networks
Junyu Liu, Min Sheng, Kan Wang +1
Capable of significantly reducing cell size and enhancing spatial reuse, network densification is shown to be one of the most dominant approaches to expand network capacity. Due to…
Effects of Base-Station Spatial Interdependence on Interference Correlation and Network Performance
Juan Wen, Min Sheng, Kaibin Huang +1
The spatial-and-temporal correlation of interference has been well studied in Poisson networks where the interfering base stations (BSs) are independent of each other. However, the…
