False Target Detection in OFDM-based Joint RADAR-Communication Systems

no code implementations26 Mar 2023 Antonios Argyriou

Joint RADAR communication (JRC) systems that use orthogonal frequency division multiplexing (OFDM) can be compromised by an adversary that re-produces the received OFDM signal creating thus false RADAR targets.

Range-Doppler Spoofing in OFDM Signals for Preventing Wireless Passive Emitter Tracking

no code implementations12 Mar 2023 Antonios Argyriou

Passive emitter tracking (PET) algorithms can estimate both the range and Doppler of a wireless emitter when it uses orthogonal frequency division multiplexing (OFDM).

Obfuscation of Human Micro-Doppler Signatures in Passive Wireless RADAR

no code implementations6 Mar 2023 Antonios Argyriou

When wireless communication signals impinge on a moving human they are affected by micro-Doppler.

Doppler Spoofing in OFDM Wireless Communication Systems

no code implementations29 Dec 2022 Antonios Argyriou, Dimitrios Kosmanos

In this paper we present a method that prevents an unauthorized receiver (URx) from correctly estimating the Doppler shift present in an orthogonal frequency division multiplexing (OFDM) wireless signal.

360-Attack: Distortion-Aware Perturbations From Perspective-Views

no code implementations CVPR 2022 Yunjian Zhang, Yanwei Liu, Jinxia Liu, Jingbo Miao, Antonios Argyriou, Liming Wang, Zhen Xu

In this paper, we propose an adversarial attack targeting spherical images, called 360-attactk, that transfers adversarial perturbations from perspective-view (PV) images to a final adversarial spherical image.

Data-Driven Modulation and Antenna Classification of Wireless Digital Communication Signals

no code implementations20 Nov 2020 Apostolos Pappas, Antonios Argyriou

The two sub-problems of modulation and number of transmitter antenna classification are initially examined independently for a variety for system parameters, namely the SNR, number of receiver (Rx) antennas, and classification algorithms.
