Optimal Transmit Power and Flying Location for UAV Covert Wireless Communications
Shihao Yan, Stephen V. Hanly, Iain B. Collings
This paper jointly optimizes the flying location and wireless communication transmit power for an unmanned aerial vehicle (UAV) conducting covert operations. This is motivated by a…
Robust Adaptive Beam Tracking for Mobile Millimetre Wave Communications
Chunshan Liu, Min Li, Lou Zhao +4
Millimetre wave (mmWave) beam tracking is a challenging task because tracking algorithms are required to provide consistent high accuracy with low probability of loss of track and…
Millimeter-Wave Beam Search with Iterative Deactivation and Beam Shifting
Chunshan Liu, Min Li, Lou Zhao +3
Millimeter Wave (mmWave) communications rely on highly directional beams to combat severe propagation loss. In this paper, an adaptive beam search algorithm based on spatial scanni…
A Kronecker-Based Sparse Compressive Sensing Matrix for Millimeter Wave Beam Alignment
Erfan Khordad, Iain B. Collings, Stephen V. Hanly
Millimeter wave beam alignment (BA) is a challenging problem especially for large number of antennas. Compressed sensing (CS) tools have been exploited due to the sparse nature of…
Explore and Eliminate: Optimized Two-Stage Search for Millimeter-Wave Beam Alignment
Min Li, Chunshan Liu, Stephen V. Hanly +2
Swift and accurate alignment of transmitter (Tx) and receiver (Rx) beams is a fundamental design challenge to enable reliable outdoor millimeter-wave communications. In this paper,…
Multi-Timescale Online Optimization of Network Function Virtualization for Service Chaining
Xiaojing Chen, Wei Ni, Tianyi Chen +4
Network Function Virtualization (NFV) can cost-efficiently provide network services by running different virtual network functions (VNFs) at different virtual machines (VMs) in a c…
