Presenter: Dr. Kawon Han
About this topic:
This presentation provides a comprehensive overview of Orthogonal Frequency Division Multiplexing (OFDM)-based Integrated Sensing and Communications (ISAC), a pivotal technology for next-generation 6G wireless networks. First, the presenter will examine the fundamental concepts of extending conventional communication systems to include radar sensing capabilities from a communication-centric ISAC perspective. He will then introduce a standard-compatible OFDM-ISAC framework that utilizes data payloads for radar sensing and investigate the fundamental trade-off between communication and sensing performance through rigorous theoretical analysis. Particular emphasis is placed on how modulation constellations and receiver designs affect sensing performance, specifically regarding range estimation accuracy and radar receiver architectures. Building upon this analysis, he will present an ISAC constellation design capable of flexibly balancing sensing and communication performance, validated through experimental results and prototype implementations. Furthermore, he addresses a new security vulnerability in ISAC systems, sensing privacy, and propose a solution via ambiguity function engineering. Finally, he will outline the remaining open challenges and future research directions necessary for ISAC to achieve practical, standard-compatible deployment in the 6G era.
