Intelligent OFDM telecommunication system. Part 3. Anti-eavesdropping and anti-jamming properties of system, based on many-parameter wavelet and Golay transforms [PDF]

open access: yes, 2019
In this paper, we aim to investigate the superiority and practicability of many-parameter Fourier transforms (MPFT) from the physical layer security (PHY-LS) perspective.

Mitigating Jamming Attacks Using Energy Harvesting

open access: yes, 2019
The use of energy harvesting as a counter-jamming measure is investigated on the premise that part of the harmful interference can be harvested to increase the transmit power.

Intelligent OFDM telecommunication system. Part 4. Anti-eavesdropping and anti-jamming properties of the system, based on many-parameter and fractional Fourier transforms [PDF]

open access: yes, 2019
In this paper, we aim to investigate the superiority and practicability of many-parameter wavelet and Golay transforms (MPWT and MPGT) from the physical layer security (PHY-LS) perspective.

Anti-jamming techniques for multichannel SAR imaging [PDF]

open access: yes, 2004
An airborne broadband jammer present in the mainbeam of a Synthetic Aperture Radar (SAR) can potentially destroy a large region of the SAR image. In addition to this, multipath reflections from the ground, known as hotclutter or terrain scattered ...

Defeating jamming with the power of silence: a game-theoretic analysis

open access: yes, 2014
The timing channel is a logical communication channel in which information is encoded in the timing between events. Recently, the use of the timing channel has been proposed as a countermeasure to reactive jamming attacks performed by an energy ...

Deep reinforcement learning-empowered anti-jamming strategy aided by sample information entropy

open access: yesTongxin xuebao
For the deep reinforcement learning (DRL)-empowered intelligent jamming, an anti-jamming strategy aided by sample information entropy was proposed. Firstly, the anti-jamming strategy network and entropy prediction network were designed based on neural ...

On the Impact of Wireless Jamming on the Distributed Secondary Microgrid Control

open access: yes, 2016
The secondary control in direct current microgrids (MGs) is used to restore the voltage deviations caused by the primary droop control, where the latter is implemented locally in each distributed generator and reacts to load variations.

Interference-Aware Cooperative Anti-Jamming Distributed Channel Selection in UAV Communication Networks

open access: yesApplied Sciences, 2018
This paper investigates the cooperative anti-jamming distributed channel selection problem in UAV communication networks. Considering the existence of malicious jamming and co-channel interference, we design an interference-aware cooperative anti-jamming
