Adaptive End-to-End Transceiver Design for NextG Pilot-Free and CP-Free Wireless Systems
Jiaming Cheng, Wei Chen, Bo Ai
The advent of artificial intelligence (AI)-native wireless communication is fundamentally reshaping the design paradigm of next-generation (NextG) systems, where intelligent air in…
Distribution-Aligned Representation Adaptation for DJSCC over Hybrid Wireless-Wired Networks
Jiangyuan Guo, Wei Chen, Yuxuan Sun +1
Deep joint source-channel coding (DJSCC) has emerged as a robust alternative to traditional separate coding for communications through wireless channels. Existing DJSCC approaches…
Age of Information Aided Intelligent Grant-Free Massive Access for Heterogeneous mMTC Traffic
Zhongwen Sun, Wei Chen, Yuxuan Sun +1
With the arrival of 6G, the Internet of Things (IoT) traffic is becoming more and more complex and diverse. To meet the diverse service requirements of IoT devices, massive machine…
Multimodal LLM Integrated Semantic Communications for 6G Immersive Experiences
Yusong Zhang, Yuxuan Sun, Lei Guo +3
6G networks promise revolutionary immersive communication experiences including augmented reality (AR), virtual reality (VR), and holographic communications. These applications dem…
Uplink Assisted Joint Channel Estimation and CSI Feedback: An Approach Based on Deep Joint Source-Channel Coding
Yiran Guo, Wei Chen, Bo Ai
In frequency division duplex (FDD) multiple-input multiple-output (MIMO) wireless communication systems, the acquisition of downlink channel state information (CSI) is essential fo…
Hierarchy-Aware and Channel-Adaptive Semantic Communication for Bandwidth-Limited Data Fusion
Lei Guo, Wei Chen, Yuxuan Sun +3
Obtaining high-resolution hyperspectral images (HR-HSI) is costly and data-intensive, making it necessary to fuse low-resolution hyperspectral images (LR-HSI) with high-resolution…
Joint CSI Estimation-Feedback-Precoding via DJSCC for MU-MIMO OFDM Systems
Yiran Guo, Wei Chen, Bo Ai +1
As the number of antennas in frequency-division duplex (FDD) multiple-input multiple-output (MIMO) systems increases, acquiring channel state information (CSI) becomes increasingly…
