Deep-Learning-Based Channel Estimation for IRS-Assisted ISAC System

no code implementations29 Jan 2024 Yu Liu, Ibrahim Al-Nahhal, Octavia A. Dobre, Fanggang Wang

A deep-learning framework is proposed to estimate the sensing and communication (S&C) channels in such a system.

Deep-Learning Channel Estimation for IRS-Assisted Integrated Sensing and Communication System

no code implementations29 Jan 2024 Yu Liu, Ibrahim Al-Nahhal, Octavia A. Dobre, Fanggang Wang

This problem is challenging due to the lack of signal processing capacity in passive IRS, as well as the presence of mutual interference between sensing and communication (SAC) signals in ISAC systems.

Deep Reinforcement Learning for RIS-Assisted FD Systems: Single or Distributed RIS?

no code implementations15 Aug 2022 Alice Faisal, Ibrahim Al-Nahhal, Octavia A. Dobre, Telex M. N. Ngatched

It is further shown that the proposed algorithm significantly improves the sum-rate compared to the non-optimized scenario in both single and distributed RIS deployment schemes.
