Reconfigurable Holographic Surfaces-Enhanced ISAC Framework for 6G Networks

This paper proposes a novel Integrated Sensing and Communication (ISAC) architecture for 6G networks, leveraging Reconfigurable Holographic Surfaces (RHS) to enhance system efficiency and performance. By integrating analog and digital beamforming techniques, the proposed RHS-ISAC model addresses the challenges of interference and Rayleigh fading in dense wireless environments. The performance analysis reveals that incorporating RHS metasurface elements significantly improves the Signal-to-Interference-plus-Noise Ratio (SINR) and reduces the Bit Error Rate (BER), demonstrating the system’s capability to achieve reliable communication and accurate sensing. The proposed architecture offers a scalable and cost-effective solution for multi-user and multi-target scenarios, making it highly suitable for real-world 6G applications. Future research will focus on optimizing metasurface design and adaptive beamforming strategies to further enhance flexibility and robustness. This study establishes RHS-ISAC as a transformative technology, paving the way for unified sensing and communication in next-generation networks.
