Hierarchical Codebook Design for Near-Field MmWave MIMO Communications Systems
Jiawei Chen, Feifei Gao, Mengnan Jian +1
Communications system with analog or hybrid analog/digital architectures usually relies on a pre-defined codebook to perform beamforming. With the increase in the size of the anten…
Electromagnetic Channel Model for Near Field MIMO Systems in The Half Space
Yuhua Jiang, Feifei Gao
In most multiple-input multiple-output (MIMO) communication systems, the amount of information that can be transmitted reliably depends on the effective degrees of freedom (EDoF) o…
RIS Design for CRB Optimization in Source Localization with Electromagnetic Interference
Yuhua Jiang, Yuanwan Mai, Feifei Gao
Reconfigurable Intelligent Surface (RIS) plays an important role in enhancing source localization accuracy. Based on the information inequality of Fisher information analyses, the…
Joint Channel Estimation and Data Detection for Hybrid RIS aided Millimeter Wave OTFS Systems
Muye Li, Shun Zhang, Yao Ge +2
For high mobility communication scenario, the recently emerged orthogonal time frequency space (OTFS) modulation introduces a new delay-Doppler domain signal space, and can provide…
Towards Semantic Communications: Deep Learning-Based Image Semantic Coding
Danlan Huang, Feifei Gao, Xiaoming Tao +2
Semantic communications has received growing interest since it can remarkably reduce the amount of data to be transmitted without missing critical information. Most existing works…
Vision-Aided Blockage Avoidance in UAV-assisted V2X Communications
Ruijin Ding, Weihua Xu, Wanmai Yuan +1
The blockage is a key challenge for millimeter wave communication systems, since these systems mainly work on line-of-sight (LOS) links, and the blockage can degrade the system per…
