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…
The Resurrection of Spectrum Spreading for 6G and Beyond: From Sinusoids to Chirps
Hyeon Seok Rou, Giuseppe Thadeu Freitas de Abreu, Emil Björnson +2
Orthogonal frequency-division multiplexing (OFDM) and its static sinusoidal subcarriers have underpinned the 4G and 5G eras, delivering high spectral efficiency and resilience to m…
Occlusion-Aware Multimodal Beam Prediction and Pose Estimation for mmWave V2I
Abidemi Orimogunje, Hyunwoo Park, Kyeong-Ju Cha +3
We propose an occlusion-aware multimodal learning framework that is inspired by simultaneous localization and mapping (SLAM) concepts for trajectory interpretation and pose predict…
System-Level Comparison of Multimodal and In-Band mmWave Sensing for Beam Prediction in 6G ISAC
Abidemi Orimogunje, Hyunwoo Park, Igbafe Orikumhi +2
Integrated sensing and communication (ISAC) can reduce beam-training overhead in mmWave vehicle-to-infrastructure (V2I) links by enabling in-band sensing-based beam prediction, whi…
