Bistatic Integrated Sensing and Communications with Flexible Intelligent Metasurfaces
Iván Alexander Morales Sandoval, Thushar Venkataramanaiah, Kuranage Roche Rayan Ranasinghe +3
We propose a novel doubly-dispersive (DD) multiple-input multiple-output (MIMO) channel model incorporating flexible intelligent metasurfaces (FIMs), suitable for integrated sensin…
Multi-Chirp AFDM for Rydberg Atomic Quantum Receivers: Waveform and Algorithm Design
Hanvit Kim, Hyeon Seok Rou, Kihong Min +2
The paper introduces a multi‑chirp affine frequency division multiplexing (MC‑AFDM) waveform and a sequential OMP‑based algorithm to enable accurate joint delay‑Doppler estimation…
Joint Synchronization and Radar Parameter Estimation for OFDM-based DISAC Systems
Niclas Führling, Hyeon Seok Rou, Kuranage Roche Rayan Ranasinghe +2
We propose a novel approach to the synchronization paradigm in distributed ISAC (DISAC) systems in doubly-dispersive (DD) channel environments via a joint synchronization and radar…
On the Robustness of AFBM Sensing to Power Amplifier Nonlinearities
Eya Gourar, Henrique L. Senger, Gustavo P. Gonçalves +6
We investigate the impact of power amplifier (PA) nonlinearities on the sensing performance of affine filter bank modulation (AFBM). While AFBM offers several advantageous properti…
AFDM as a Software Upgrade of OFDM: One Firmware Patch, a New Frontier
Hyeon Seok Rou, Giuseppe Thadeu Freitas de Abreu
In this white paper, we summarize for the benefit of the wider research community on wireless communications, the two key results that we shared with the attendees of the 2026 IEEE…
Reciprocal Beyond Diagonal Reconfigurable Intelligent Surface: Distributed Scattering Matrix Design and MIMO Beamforming via Fractional Programming and Manifold Optimization
Iván Alexander Morales Sandoval, Marko Fidanovski, Hyeon Seok Rou +2
We consider the optimization of beyond diagonal reconfigurable intelligent surface (BD-RIS)-aided multi-user (MU) cell-free (CF)-massive multiple-input multiple-output (mMIMO) syst…
