ParaJSCC: A Parameterized Framework for Reusable Multimodal Joint Source-Channel Coding
Kemi Chen, Mingkai Chen, Youjia Chen +3
Multimodal signals, such as visual, audio, and tactile data, are increasingly maintained as persistent digital assets in immersive communication systems and digital twins. In these…
Federated Customization of Large Models: Approaches, Experiments, and Insights
Yuchuan Ye, Ming Ding, Youjia Chen +2
In this article, we explore federated customization of large models and highlight the key challenges it poses within the federated learning framework. We review several popular lar…
Hybrid Relay-Reflecting Intelligent Surface-Aided Covert Communications
Jinsong Hu, Xiaoqiang Shi, Youjia Chen +2
In this paper, we propose to use a hybrid relay-reflecting intelligent surface (HR-RIS) to enhance the performance of a covert communication system. Specifically, the HR-RIS consis…
Analyzing the Impact of Molecular Re-Radiation on the MIMO Capacity in High-Frequency Bands
Sayed Amir Hoseini, Ming Ding, Mahbub Hassan +1
In this paper, we show how the absorption and re-radiation energy from molecules in the air can influence the Multiple Input Multiple Output (MIMO) performance in high-frequency ba…
Directional Modulation-Enabled Secure Transmission with Intelligent Reflecting Surface
Liangling Lai, Jinsong Hu, Youjia Chen +2
We propose a new secure transmission scheme which uses directional modulation (DM) with artificial noise and is aided by the intelligent reflecting surface (IRS). Specifically, the…
Establishing Secrecy Region for Directional Modulation Scheme with Random Frequency Diverse Array
Shengping Lv, Jinsong Hu, Youjia Chen +3
Random frequency diverse array (RFDA) based directional modulation (DM) was proposed as a promising technology in secure communications to achieve a precise transmission of confide…
Distributed Caching for Data Dissemination in the Downlink of Heterogeneous Networks
Jun Li, Youjia Chen, Zihuai Lin +3
Heterogeneous cellular networks (HCN) with embedded small cells are considered, where multiple mobile users wish to download network content of different popularity. By caching dat…
Pricing and Resource Allocation via Game Theory for a Small-Cell Video Caching System
Jun Li, He Chen, Youjia Chen +3
Evidence indicates that downloading on-demand videos accounts for a dramatic increase in data traffic over cellular networks. Caching popular videos in the storage of small-cell ba…
