Wireless Covert Communications Aided by Distributed Cooperative Jamming Over Slow Fading Channels [PDF]
IEEE Transactions on Wireless Communications, 2021 In this paper, we study covert communications between a pair of legitimate transmitter-receiver against a watchful warden over slow fading channels. There coexist multiple friendly helper nodes who are willing to protect the covert communication from ...

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023 Methods based on convolutional neural networks (CNNs) have become a vital offshoot for hyperspectral image (HSI) classification. In recent years, the 3-D CNN (3-DCNN) has become dominant due to its excellent capability of extracting features.

New Jamming Scenario: From Marginal Jamming to Deep Jamming [PDF]
Physical Review Letters, 2011 We study properties of jammed packings of frictionless spheres over a wide range of volume fractions. There exists a crossover volume fraction which separates deeply jammed solids from marginally jammed solids. In deeply jammed solids, all the scalings presented in marginally jammed solids are replaced with remarkably different ones with potential ...

Statistical Analysis of Bistatic Radar Ground Clutter for Different German Rural Environments
Sensors, 2020 This article presents the statistical analysis of bistatic radar rural ground clutter for different terrain types under low grazing angles. Compared to most state-of-the-art analysis, we present country-specific clutter analysis for subgroups of rural ...

Intelligent Radar Jamming Recognition in Open Set Environment Based on Deep Learning Networks
Remote Sensing, 2022 Jamming recognition is an essential step in radar detection and anti-jamming in the complex electromagnetic environment. When radars detect an unknown type of jamming that does not occur in the training set, the existing radar jamming recognition ...

CHI '13 Extended Abstracts on Human Factors in Computing Systems, 2013 Game Jams - energized, fast-paced get-togethers of developers and artists to make digital games - have recently emerged as a way to generate and inspire novel game ideas and new ways of thinking. We intend to introduce the CHI community to this collaborative, fast-paced method of design by holding a game jam with an emphasis on developing novel user ...
