Jamming-resistant communication is crucial for safety-critical applications such as emergency alert broadcasts or the dissemination of navigation signals in adversarial conditions. Interference due to intentional/unintentional jamming, co-channel and adjacent channel users can cause severe performance degradation to the communication receivers. Several studies on Electronic Attacks (EAs) to the...

Abstract While interference mitigation techniques can significantly improve the performance of a Global Navigation Satellite System (GNSS) receiver in presence jamming, they also introduce distortions, biases and delays on GNSS measurements final solution. We analyze impact five solution provided by timing that operates known location under static conditions. In this configuration, only estimat...

This paper analyzes the influence of the space-time signal processing technique on the performance of GPS signal acquisition in conditions of strong broadband interference (jamming) and multipath. The space-time processing method used for effective mitigation of GPS interference before processing by a conventional acquisition algorithm is the Minimum Variance Distortionless Response beamforming...

In multihop ad hoc networks, a jammer can drastically disrupt the flow of information by intentionally interfering with links between a subset of nodes. The impact of such attacks can escalate when the jammer is moving. As a countermeasure for such attacks, adaptive beamforming techniques can be employed for spatial filtering of the jamming signal. This paper investigates the performance of ada...

Spoofing attacks can completely mislead the position solution provided by global navigation satellite systems (GNSS). Recently, several anti-spoofing techniques have been introduced to combat spoofing attacks. However, in most cases the available anti-spoofing techniques are computationally complex or limited to a specific spoofing scenario. This paper provides a low computational complexity ap...

This work presents efficient connection provisioning techniques mitigating high-power jamming attacks in spectrally-spatially flexible optical networks (SS-FONs) utilizing multicore fibers. High-power are modeled based on their impact the lightpaths’ quality of transmission (QoT) through inter-core crosstalk. Based a desired threshold lightpath’s QoT, modulation format used, length path, as wel...

This paper presents design and implementation of three new Infrared Counter-Countermeasure (IRCCM) efficient methods using Neural Network (NN), Fuzzy System (FS), and Kalman Filter (KF). The proposed algorithms estimate tracking error or correction signal when jamming occurs. An experimental test setup is designed and implemented for performance evaluation of the proposed methods. The methods v...
