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论和无线通信方面的研究项目。该研究计划涉及开发先进的联合源信道编码（JSCC）技术，以提高无线通信网络的可靠性、连接性和速度，并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 提供了构建最佳编码的正确方法，以便在噪声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，以及对于香农数据压缩和信道编码分离原理无法成立的多用户网络一般来说。基于我们在 JSCC 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）研究多网络信息编码和传输的基本信息论极限，即容量和 JSCC 误差指数。用户网络并以可忽略不计的损失恢复它； (2) 开发复杂但易于分析处理的离散信道模型，以明智地表示与多个天线和软决策解调一起使用的无线（相关衰落）网络的行为； (3) 无线网络强大的低复杂性 JSCC 技术的设计、构建和分析，以及无线多媒体通信和节能传感器网络的应用。拟议的研究将以每年 8 名高素质人员的严格培训为特色（3博士生、硕士生 2 名、本科生 2 名，以及博士后 1 名），让他们沉浸在信息论和无线通信领域及时具有挑战性的主题中，并产出创新的高质量出版物。该研究项目的结果预计将加深对 JSCC 基本原理和实践方面的理解，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。
