A Hybrid Frame Structure Design of OTFS for Multi-tasks Communications
Pu Yuan, Jin Liu, Dajie Jiang +1
Orthogonal time frequency space (OTFS) is a promising waveform in high mobility scenarios for it fully exploits the time-frequency diversity using a discrete Fourier transform (DFT…
KernelGPA: A Globally Optimal Solution to Deformable SLAM in Closed-form
Fang Bai, Kanzhi Wu, Adrien Bartoli
We study the generalized Procrustes analysis (GPA), as a minimal formulation to the simultaneous localization and mapping (SLAM) problem. We propose KernelGPA, a novel global regis…
Low-Complex Channel Estimation in Extra-Large Scale MIMO with the Spherical Wave Properties
Xumin Pu, Zhinan Sun, Qianbin Chen +1
This paper investigates the low-complex linear minimum mean squared error (LMMSE) channel estimation in an extra-large scale MIMO system with the spherical wave model (SWM). We mod…
ROMO: Retrieval-enhanced Offline Model-based Optimization
Mingcheng Chen, Haoran Zhao, Yuxiang Zhao +4
Data-driven black-box model-based optimization (MBO) problems arise in a great number of practical application scenarios, where the goal is to find a design over the whole space ma…
SwinFace: A Multi-task Transformer for Face Recognition, Expression Recognition, Age Estimation and Attribute Estimation
Lixiong Qin, Mei Wang, Chao Deng +4
In recent years, vision transformers have been introduced into face recognition and analysis and have achieved performance breakthroughs. However, most previous methods generally t…
Joint Beam Management and SLAM for mmWave Communication Systems
Hang Que, Jie Yang, Chao-Kai Wen +3
The millimeter-wave (mmWave) communication technology, which employs large-scale antenna arrays, enables inherent sensing capabilities. Simultaneous localization and mapping (SLAM)…
