Rydberg Atomic Quantum Radio: A Comprehensive Survey From Wireless Communication Perspective
Yiyue Xiang, Neng Ye, Qihao Peng +5
Next-generation space-air-ground-sea integrated networks (SAGSIN) impose unprecedented demands on advanced radio frequency (RF) receivers for full-spectrum agility, ultra-high sens…
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…
Low-Complexity Soft-Feedback Detector for AFDM Systems
Taohe Chen, Yin Xu, Tianyao Ma +4
Affine frequency division multiplexing (AFDM), an emerging multi-carrier modulation scheme, has garnered significant attention due to its resilience to Doppler shifts and capabilit…
Discrete-Time CRLB-based Power Allocation for CF MIMO-ISAC with Joint Localization and Velocity Sensing
Guoqing Xia, Pei Xiao, Qu Luo +4
In this paper, we investigate integrated sensing and communication (ISAC) in a cell-free (CF) multiple-input multiple-output (MIMO) network, where each access point functions eithe…
Enhanced Ground-Satellite Direct Access via Onboard Rydberg Atomic Quantum Receivers
Qihao Peng, Tierui Gong, Zihang Song +4
Ground-satellite links for 6G networks face critical challenges, including severe path loss, tight size-weight-power limits, and congested spectrum, all of which significantly hind…
Rydberg Atomic Quantum Satellites for Enhanced Ground-to-Space Direct Uplink Access
Qihao Peng, Tierui Gong, Zihang Song +4
This paper investigates the performance advantages of Rydberg atomic quantum (RAQ)-based multiple-input multiple-output (MIMO) satellites for enhancing direct ground-to-space uplin…
