Two-Bit RIS-Aided Communications at 3.5GHz: Some Insights from the Measurement Results Under Multiple Practical Scenes
Shun Zhang, Haoran Sun, Runze Yu +6
In this paper, we propose a two-bit reconfigurable intelligent surface (RIS)-aided communication system, which mainly consists of a two-bit RIS, a transmitter and a receiver. A cor…
YOLO: An Efficient Terahertz Band Integrated Sensing and Communications Scheme with Beam Squint
Hongliang Luo, Feifei Gao, Hai Lin +2
Using communications signals for dynamic target sensing is an important component of integrated sensing and communications (ISAC). In this paper, we propose to utilize the beam squ…
Multi-User Matching and Resource Allocation in Vision Aided Communications
Weihua Xu, Feifei Gao, Yong Zhang +2
Visual perception is an effective way to obtain the spatial characteristics of wireless channels and to reduce the overhead for communications system. A critical problem for the vi…
Pay Less But Get More: A Dual-Attention-based Channel Estimation Network for Massive MIMO Systems with Low-Density Pilots
Binggui Zhou, Xi Yang, Shaodan Ma +2
To reap the promising benefits of massive multiple-input multiple-output (MIMO) systems, accurate channel state information (CSI) is required through channel estimation. However, d…
Environment Semantics Aided Wireless Communications: A Case Study of mmWave Beam Prediction and Blockage Prediction
Yuwen Yang, Feifei Gao, Xiaoming Tao +2
In this paper, we propose an environment semantics aided wireless communication framework to reduce the transmission latency and improve the transmission reliability, where semanti…
Radar Sensing via OTFS Signaling: A Delay Doppler Signal Processing Perspective
Kecheng Zhang, Weijie Yuan, Shuangyang Li +4
The recently proposed orthogonal time frequency space (OTFS) modulation multiplexes data symbols in the delay-Doppler (DD) domain. Since the range and velocity, which can be derive…
Vision Aided Environment Semantics Extraction and Its Application in mmWave Beam Selection
Feiyang Wen, Weihua Xu, Feifei Gao +2
In this letter, we propose a novel mmWave beam selection method based on the environment semantics extracted from user-side camera images. Specifically, we first define the environ…
A Generalized Semantic Communication System: from Sources to Channels
Zhijin Qin, Feifei Gao, Bo Lin +3
Semantic communication is regarded as the breakthrough beyond the Shannon paradigm, which transmits only semantic information to significantly improve communication efficiency. Thi…
