Joint Channel Estimation, Detection, and Resource Allocation for OTFS-RSMA
Chaedam Son, Si-Hyeon Lee
Orthogonal time frequency space (OTFS) modulation is well suited for high-mobility communications, but channel estimation and efficient multi-user transmission remain challenging.…
Tracking-Assisted Robust Secure Transmission Against a Mobile Eavesdropper in Cell-Free ISAC Networks
Jong-Hyuk Hong, Chaedam Son, Si-Hyeon Lee
In this paper, we propose a tracking-assisted robust secure transmission framework for cell-free integrated sensing and communication (ISAC) networks that exploits distributed mult…
Robust Beamforming and Time Allocation for Time-Division Cell-Free Near-Field ISAC
Chaedam Son, Si-Hyeon Lee
In this paper, we propose a time-division near-field integrated sensing and communication (ISAC) framework for cell-free multiple-input multiple-output (MIMO), where sensing and do…
Secrecy Enhancement for UAV-enabled Integrated Sensing and Communication System
Chaedam Son, Seongah Jeong
In this correspondence, we propose an unmanned aerial vehicle (UAV)-enabled integrated sensing and communication (ISAC) system, where a full-duplex UAV equipped with uniform planar…
