Super Fast Beam and Channel Tracking in 2D Phased Antenna Arrays
Yu Liu, Jiahui Li, Yin Sun +1
Millimeter wave (mmWave) is an attractive candidate for high-speed mobile communications in the future. However, due to the propagation characteristics of mmWave, beam and and and…
Coverage Probability Analysis of UAV Cellular Networks in Urban Environments
Lai Zhou, Zhi Yang, Shidong Zhou +1
In this paper, we study coverage probabilities of the UAV-assisted cellular network modeled by 2-dimension (2D) Poisson point process. The cellular user is assumed to connect to th…
Channel Model in Urban Environment for Unmanned Aerial Vehicle Communications
Zhi Yang, Lai Zhou, Guangyue Zhao +1
In order to develop and analyze reliable communications links for unmanned aerial vehicles (UAVs), accurate models for the propagation channel are required. The radio channel prope…
Blockage Modeling for Inter-layer UAVs Communications in Urban Environments
Zhi Yang, Lai Zhou, Guangyue Zhao +1
The impact of buildings blockage on the UAVs communications in different UAVs heights is studied, when UAVs fly in a given rectangular urban area. This paper analyzes the propertie…
Joint Beam and Channel Tracking for Two-Dimensional Phased Antenna Arrays
Yu Liu, Jiahui Li, Yin Sun +1
Analog beamforming is a low-cost architecture for millimeter-wave (mmWave) mobile communications. However, it has two disadvantages for serving fast mobility users: (i) the mmWave…
How to Mobilize mmWave: A Joint Beam and Channel Tracking Approach
Jiahui Li, Yin Sun, Limin Xiao +2
Maintaining reliable millimeter wave (mmWave) connections to many fast-moving mobiles is a key challenge in the theory and practice of 5G systems. In this paper, we develop a new a…
