Flexible Wideband Filtering Monopole Antenna With Stable High Omnidirectionality
Runkai Song, Fan Qin, Chao Gu +3
This article presents a wideband flexible filtering monopole antenna with symmetric structure for stable high omnidirectionality. It is based on a monopole antenna, which is printe…
Toward Alias-Free Channel Extrapolation in Upper Mid-Band Systems: A Spatial-Frequency-Temporal Tensor Learning Approach
Jiawei Zhuang, Hongwei Hou, Yafei Wang +4
Upper mid-band massive multiple-input multiple-output (MIMO) offers a favorable capacity-coverage trade-off for next-generation wireless systems, but its large antenna arrays, wide…
Cell-Level Channel Shaping for Rydberg Atomic Quantum Receivers in Satellite Uplinks With Doppler-Enabled Superheterodyne Reception
Qihao Peng, Qu Luo, Kezhi Wang +4
In this paper, we propose a self-superheterodyne Rydberg uniform array receiver for satellite uplink communications, in which the Doppler shift naturally induced by satellite motio…
Explainable Task-Oriented Token Communication for AI-Native 6G Networks
Feibo Jiang, Lei Mao, Li Dong +3
The integration of Foundation Models (FMs) and wireless communications is driving the evolution of image communication from bit-accurate transmission toward task-oriented transmiss…
A Hybrid Near-field Indoor Channel Model for THz Bands Based on Surface Scattering Characteristics
Yongchao He, Taihao Zhang, Cunhua Pan +6
Terahertz (THz) communication and extremely large-scale MIMO (XL-MIMO) are essential for achieving ultra-high data rates in future 6G systems. However, at sub-millimeter wavelength…
Beyond the RF Paradigm: Rydberg Atomic Receivers for Next-Generation IoT
Qihao Peng, Qu Luo, Dongnan Xia +11
Next-generation Internet-of-Things (IoT) is evolving toward a ubiquitous, ultra-low-power, and multi-band heterogeneous networking paradigm that seamlessly integrates terrestrial,…
