Anti-Jamming Precoding Against Disco Intelligent Reflecting Surfaces Based Fully-Passive Jamming Attacks [PDF]
IEEE Transactions on Wireless Communications, 2023 Emerging intelligent reflecting surfaces (IRSs) significantly improve system performance, but also pose a huge risk for physical layer security. Existing works have illustrated that a disco IRS (DIRS), i.e., an illegitimate IRS with random time-varying ...

An iALM-ICA-based Anti-Jamming DS-CDMA Receiver for LMS Systems
, 2018 We consider a land mobile satellite communication system using spread spectrum techniques where the uplink is exposed to MT jamming attacks, and the downlink is corrupted by multi-path fading channels. We proposes an anti-jamming receiver, which exploits

Massive MIMO Pilot Retransmission Strategies for Robustification against Jamming [PDF]
, 2017 This letter proposes anti-jamming strategies based on pilot retransmission for a single user uplink massive MIMO under jamming attack. A jammer is assumed to attack the system both in the training and data transmission phases.

Droplet: A New Denial-of-Service Attack on Low Power Wireless Sensor Networks [PDF]
, 2013 In this paper we present a new kind of Denial-of-Service attack against the PHY layer of low power wireless sensor networks. Overcoming the very limited range of jamming-based attacks, this attack can penetrate deep into a target network with high power ...

A Real-Time Phase Center Variation Compensation Algorithm for the Anti-Jamming GNSS Antennas
IEEE Access, 2020 The anti-jamming antenna is one of the most efficient ways to resist the adversary effect of the interference signal in GNSS positioning. Most anti-jamming antennas can adaptively adjust the radiation figure of the antenna to minimize the interference ...

A multi‐agent reinforcement learning anti‐jamming method with partially overlapping channels
IET Communications, 2021 This paper investigates the problem of multi‐user anti‐jamming channel access with partially overlapping channels (POC). Compared with traditional anti‐jamming systems that use non‐overlapping channels, POC improve the spectral efficiency.
