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.
