Normalized Ambiguity Function Characteristics of OFDM, OTFS, AFDM, and CP-AFDM for ISAC
Hyeon Seok Rou, Giuseppe Thadeu Freitas de Abreu
This paper presents a unified and system-agnostic analysis of the ambiguity function (AF) characteristics of four representative multicarrier waveforms, orthogonal frequency divisi…
The IEEE Signal Processing Society's Leading Role in Developing Standards for Computational Imaging and Sensing: Part II
Andreas Bathelt, Benjamin Deutschmann, Hyeon Seok Rou +3
In every imaging or sensing application, the physical hardware creates constraints that must be overcome or they limit system performance. Techniques that leverage additional degre…
On the Noise Robustness of Affine Frequency Division Multiplexing: Analysis and Applications
Vincent Savaux, Steve Sawadogo, Hyeon Seok Rou +1
This paper investigates the robustness of affine frequency division multiplexing (AFDM) and orthogonal time frequency space (OTFS) modulation schemes against non-white Gaussian noi…
Secrecy-Driven Beamforming for Multi-User Integrated Sensing and Communication
Ali Khandan Boroujeni, Hyeon Seok Rou, Ghazal Bagheri +4
This paper proposes a secure integrated sensing and communications (ISAC) framework for multi-user systems with multiple communication users (CUs) and adversarial targets, where th…
A Secure ISAC Waveform Design Framework via Random Frequency and PRI Agility
Ali Khandan Boroujeni, Hyeon Seok Rou, Ghazal Bagheri +4
This paper presents a novel framework for enhancing the security, data rate, and sensing performance of integrated sensing and communications (ISAC) systems. We employ a random fre…
Affine Filter Bank Modulation (AFBM): A Novel 6G ISAC Waveform with Low PAPR and OOBE
Kuranage Roche Rayan Ranasinghe, Henrique L. Senger, Gustavo P. Gonçalves +4
We propose the affine filter bank modulation (AFBM) waveform for enhanced integrated sensing and communications (ISAC) in sixth generation (6G), designed by drawing on concepts fro…
