Fast Accurate Beam and Channel Tracking for Two-dimensional Phased Antenna Arrays
Yu Liu, Jiahui Li, Xiujun Zhang +1
The sparsity and the severe attenuation of millimeter-wave (mmWave) channel imply that highly directional communication is needed. The narrow beam produced by large array requires…
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…
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…
Analog Beam Tracking in Linear Antenna Arrays: Convergence, Optimality, and Performance
Jiahui Li, Yin Sun, Limin Xiao +2
The directionality of millimeter-wave (mmWave) communications creates a significant challenge in serving fast-moving mobile terminals on, e.g., high-speed vehicles, trains, and UAV…
