Adaptive Plug-and-Play Channel Estimation with Consistency Models for MIMO Systems
Jinlong Li, Kexin Fang, Peng Yang +3
This paper proposes a consistency-model-based channel estimation algorithm for multiple-input multiple-output (MIMO) systems. The proposed algorithm employs a consistency model (CM…
Multimodal Large Language Model Enabled Robust Beamforming for HAP Downlink Communications
Xiaoyu Xing, Peng Yang, Guoquan Tao +3
Small changes in high altitude platform (HAP) attitude can cause significant deviations in HAP downlink beam directions, thereby severely degrading HAP downlink communication perfo…
Generative AI Agent Empowered Power Allocation for HAP Propulsion and Communication Systems
Xiaoyu Xing, Dingyi Lu, Peng Yang +3
High altitude platforms (HAPs) are emerging as a key enabler for 6G coverage, yet limited energy must be split between propulsion and communications. Most prior HAP studies ignore…
DRL-driven Online Optimization for Joint Traffic Reshaping and Channel Reconfiguration in RIS-assisted Semantic NOMA Communications
Songhan Zhao, Shimin Gong, Bo Gu +3
This paper explores a reconfigurable intelligent surface (RIS)-assisted and semantic-aware wireless network, where multiple semantic users (SUs) transmit semantic information to an…
Generative Artificial Intelligence Assisted Multi-modal Semantic Extraction for NOMA-based Image Transmissions
Songhan Zhao, Shimin Gong, Bo Gu +4
In this paper, we investigate a generative artificial intelligence (GAI)-assisted semantic communication framework for non-orthogonal multiple access (NOMA)-based image transmissio…
Entropy-and-Channel-Aware Adaptive-Rate Semantic Communication with MLLM-Aided Feature Compensation
Weixuan Chen, Qianqian Yang, Yuhao Chen +4
Despite the transmission efficiency gains of semantic communication (SemCom) over traditional methods, most existing SemCom schemes still operate at a fixed transmission rate regar…
