DFT-s-OFDM with Chirping for Integrated Sensing and Communications in 6G and Beyond
Yujie Liu, Yong Liang Guan, David González G. +1
The sixth generation (6G) of mobile communications and beyond is expected to enable advanced functionalities, such as integrated sensing and communication (ISAC), while involving d…
Quadrature Over-the-Air-Computing for Multimodal Dual-Stream Signal Processing
Hyeon Seok Rou, Kengo Ando, Giuseppe Thadeu Freitas de Abreu +1
We propose a novel quadrature over-the-air computing (Q-OTAC) framework that enables the simultaneously computation of two independent functions and/or data stream within a single…
Robust Egoistic Rigid Body Localization
Niclas Führling, Giuseppe Thadeu Freitas de Abreu, David González G. +1
We consider a robust and self-reliant (or "egoistic") variation of the rigid body localization (RBL) problem, in which a primary rigid body seeks to estimate the pose (i.e., locati…
Affine Frequency Division Multiplexing (AFDM) for 6G: Properties, Features, and Challenges
Hyeon Seok Rou, Kuranage Roche Rayan Ranasinghe, Vincent Savaux +3
Affine frequency division multiplexing (AFDM) is an emerging waveform candidate for future sixth generation (6G) systems offering a range of promising features, such as enhanced ro…
6D Rigid Body Localization and Velocity Estimation via Gaussian Belief Propagation
Niclas Führling, Volodymyr Vizitiv, Kuranage Roche Rayan Ranasinghe +4
We propose a novel message-passing solution to the sixth-dimensional (6D) moving rigid body localization (RBL) problem, in which the three-dimensional (3D) translation vector and r…
Basis Expansion Extrapolation based Long-Term Channel Prediction for Massive MIMO OTFS Systems
Yanfeng Zhang, Xu Zhu, Yujie Liu +3
Massive multi-input multi-output (MIMO) combined with orthogonal time frequency space (OTFS) modulation has emerged as a promising technique for high-mobility scenarios. However, i…
