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…
Low Probability of Detection Communication: Opportunities and Challenges
Shihao Yan, Xiangyun Zhou, Jinsong Hu +1
Low probability of detection (LPD) communication has recently emerged as a new transmission technology to address privacy and security in wireless networks. Recent studies have est…
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,…
Gaussian Signalling for Covert Communications
Shihao Yan, Yirui Cong, Stephen Hanly +1
In this work, we examine the optimality of Gaussian signalling for covert communications with an upper bound on or as th…
Precoding for the Sparsely Spread MC-CDMA Downlink with Discrete-Alphabet Inputs
Min Li, Chunshan Liu, Stephen V. Hanly
Sparse signatures have been proposed for the CDMA uplink to reduce multi-user detection complexity, but they have not yet been fully exploited for its downlink counterpart. In this…
