In this application, we seek funding to continue our research program in information theory and wireless communications. The research program concerns the development of advanced joint source-channel coding (JSCC) technologies for improving the reliability, connectivity and speed of wireless communication networks and meeting the rapidly growing demand for seamless and ubiquitous wireless multimedia services. JSCC provides the right approach to construct the best codes for the efficient transmission of data sources over noisy channels, particularly under stringent delay and complexity constraints, and for multi-user networks where Shannon's principle for the separation of data compression and channel coding fails to hold in general. Building on our experience and extensive achievements in JSCC, we will focus on the following three interconnected research thrust areas: (1) The investigation of the fundamental information-theoretic limits, namely capacity and JSCC error exponent, for coding and transmitting information over multi-user networks and recovering it with negligible loss; (2) The development of sophisticated but analytically tractable discrete channel models to judiciously represent the behavior of wireless (correlated fading) networks used with multiple antennas and soft-decision demodulation; (3) The design, construction and analysis of powerful low-complexity JSCC techniques for wireless networks, with applications to wireless multimedia communications and energy-efficient sensor networks. The proposed research will feature the rigorous training of eight highly qualified personnel per year (3 doctoral, 2 Masters and 2 undergraduate students, as well as one postdoctoral fellow), immersing them in timely challenging topics in information theory and wireless communications and resulting in innovative high-quality publications. The results of this research program are anticipated to provide a deeper understanding of both the fundamental principles and the practical aspects of JSCC, thus positively contributing to a sustainable improvement of wireless communications and multimedia technologies.

在此申请中，我们寻求资金来继续我们在信息理论和无线通信方面的研究计划。该研究项目关注先进的联合源信道编码（JSCC）技术的发展，以提高无线通信网络的可靠性、连接性和速度，满足对无缝和无处不在的无线多媒体服务快速增长的需求。JSCC提供了正确的方法来构建最佳代码，以便在有噪声的信道上有效传输数据源，特别是在严格的延迟和复杂性约束下，以及在香农分离数据压缩和信道编码的原则通常不成立的多用户网络中。基于我们在JSCC方面的经验和广泛成就，我们将重点关注以下三个相互关联的研究重点领域：(1)研究在多用户网络上编码和传输信息并以可忽略的损失恢复信息的基本信息论极限，即容量和JSCC误差指数；(2)开发复杂但易于分析的离散信道模型，以明智地表示使用多天线和软判决解调的无线（相关衰落）网络的行为；(3)无线网络中功能强大的低复杂度JSCC技术的设计、构建和分析，并应用于无线多媒体通信和节能传感器网络。本项目每年将严格培养8名高素质人才（博士3名、硕士2名、本科生2名、博士后1名），使其及时从事信息理论和无线通信领域具有挑战性的课题研究，并发表具有创新性的高质量论文。该研究项目的结果有望对JSCC的基本原理和实践方面提供更深入的理解，从而为无线通信和多媒体技术的可持续发展做出积极贡献。
