A Physical Layer Security Framework for Integrated Sensing and Semantic Communication Systems

no code implementations8 Oct 2024 Hamid Amiriara, Mahtab Mirmohseni, Ahmed Elzanaty, Yi Ma, Rahim Tafazolli

In this paper, we address a physical layer security (PLS) framework for the integrated sensing and semantic communication (ISASC) system, where a multi-antenna dual-function semantic base station serves multiple single-antenna semantic communication users (SCUs) and monitors a malicious sensing target (MST), in the presence of a single-antenna eavesdropper (EVE), with both the MST and EVE aiming to wiretap information from the SCUs' signals.

Optical ISAC: Fundamental Performance Limits and Transceiver Design

no code implementations21 Aug 2024 Alireza Ghazavi Khorasgani, Mahtab Mirmohseni, Ahmed Elzanaty

This paper characterizes the optimal capacity-distortion (C-D) tradeoff in an optical point-to-point system with single-input single-output (SISO) for communication and single-input multiple-output (SIMO) for sensing within an integrated sensing and communication (ISAC) framework.
