Superposition of PRS and PDSCH for ISAC System: Spectral Efficiency Enhancement and Range Ambiguity Elimination

no code implementations30 Sep 2024 Keivan Khosroshahi, Philippe Sehier, Sami Mekki

Moreover, we introduce the joint exploitation of PRS and demodulation reference signal (DMRS) to prevent range ambiguity in the form of ghost targets.

Doppler Ambiguity Elimination Using 5G Signals in Integrated Sensing and Communication

no code implementations1 Aug 2024 Keivan Khosroshahi, Philippe Sehier, Sami Mekki

Through simulations and analysis, we demonstrate the effectiveness of our proposed method on joint DMRS-PRS exploitation in mitigating Doppler ambiguity and the efficiency of the resource allocation scheme in achieving Pareto optimality for ISAC within a 5G NR framework.

Leveraging PRS and PDSCH for Integrated Sensing and Communication Systems

no code implementations1 Aug 2024 Keivan Khosroshahi, Philippe Sehier, Sami Mekki

To overcome this obstacle, we propose two innovative approaches for different PRS comb sizes within the ISAC framework, leveraging the demodulation reference signal (DMRS) within PDSCH to eliminate ghost targets.

Towards Distributed and Intelligent Integrated Sensing and Communications for 6G Networks

no code implementations18 Feb 2024 Emilio Calvanese Strinati, George C. Alexandropoulos, Navid Amani, Maurizio Crozzoli, Giyyarpuram Madhusudan, Sami Mekki, Francois Rivet, Vincenzo Sciancalepore, Philippe Sehier, Maximilian Stark, Henk Wymeersch

This paper introduces the distributed and intelligent integrated sensing and communications (DISAC) concept, a transformative approach for 6G wireless networks that extends the emerging concept of integrated sensing and communications (ISAC).

Smart Channel State Information Pre-processing for Joint Authentication and Secret Key Distillation

no code implementations1 Jun 2022 Muralikrishnan Srinivasan, Sotiris Skaperas, Arsenia Chorti, Mahdi Shakiba Herfeh, Muhammad K. Shehzad, Philippe Sehier

In this paper, starting from the observation that the wireless channel is a composite, deterministic / stochastic process, we propose a power domain decomposition that allows performing the two tasks simultaneously.

Context-Aware Security for 6G Wireless The Role of Physical Layer Security

no code implementations5 Jan 2021 Arsenia Chorti, Andre Noll Barreto, Stefan Kopsell, Marco Zoli, Marwa Chafii, Philippe Sehier, Gerhard Fettweis, H. Vincent Poor

Sixth generation systems are expected to face new security challenges, while opening up new frontiers towards context awareness in the wireless edge.

Deep Learning Assisted CSI Estimation for Joint URLLC and eMBB Resource Allocation

no code implementations12 Mar 2020 Hamza Khan, M. Majid Butt, Sumudu Samarakoon, Philippe Sehier, Mehdi Bennis

Multiple-input multiple-output (MIMO) is a key for the fifth generation (5G) and beyond wireless communication systems owing to higher spectrum efficiency, spatial gains, and energy efficiency.
