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…
Latency-Aware Resource Allocation for Integrated Communications, Computation, and Sensing in Cell-Free mMIMO Systems
Qihao Peng, Qu Luo, Zheng Chu +5
In this paper, we investigate a cell-free massive multiple-input and multiple-output (MIMO)-enabled integration communication, computation, and sensing (ICCS) system, aiming to min…
Index Modulation for Fluid Antenna-Assisted MIMO Communications: System Design and Performance Analysis
Jing Zhu, Gaojie Chen, Pengyu Gao +3
In this paper, we propose a transmission mechanism for fluid antennas (FAs) enabled multiple-input multiple-output (MIMO) communication systems based on index modulation (IM), name…
Exploiting Structured Sparsity with Low Complexity Sparse Bayesian Learning for RIS-assisted MIMO Channel Estimation
W. Li, Z. Lin, Q. Guo +1
As an emerging communication auxiliary technology, reconfigurable intelligent surface (RIS) is expected to play a significant role in the upcoming 6G networks. Due to its total ref…
