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…
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…
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,…
Millimeter Wave Beam Alignment: Large Deviations Analysis and Design Insights
Chunshan Liu, Min Li, Stephen V. Hanly +2
In millimeter wave cellular communication, fast and reliable beam alignment via beam training is crucial to harvest sufficient beamforming gain for the subsequent data transmission…
Design and Analysis of Transmit Beamforming for Millimetre Wave Base Station Discovery
Chunshan Liu, Min Li, Iain B. Collings +2
In this paper, we develop an analytical framework for the initial access (a.k.a. Base Station (BS) discovery) in a millimeter-wave (mm-wave) communication system and propose an eff…
Physical Layer Security in Downlink Multi-Antenna Cellular Networks
Giovanni Geraci, Harpreet S. Dhillon, Jeffrey G. Andrews +2
In this paper, we study physical layer security for the downlink of cellular networks, where the confidential messages transmitted to each mobile user can be eavesdropped by both (…
