Orbital Detection
Kuranage Roche Rayan Ranasinghe, Giuseppe Thadeu Freitas de Abreu
We introduce orbital detection (OD), a framework for designing asymptotically optimal, low-complexity message passing (MP) receivers for digitally modulated multiple-input multiple…
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…
Learning to Compute on Dirty Paper
Shreesal Shrestha, Kuranage Roche Rayan Ranasinghe, Giuseppe Thadeu Freitas de Abreu +1
We propose a fully learning-based approach to integrated communication and computing (ICC) that combines dirty paper coding (DPC) with over-the-air computation. Each user employs a…
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…
Manifold Optimization-based Pilot Allocation for Cell-Free Massive MIMO ISAC Systems
Getuar Rexhepi, Kuranage Roche Rayan Ranasinghe, Giuseppe Thadeu Freitas de Abreu
We address the challenge of pilot design in cell-free massive multiple input multiple output (CF-mMIMO) integrated sensing and communications (ISAC) systems. We propose a novel pil…
