Studies on joint source-channel coding approaches for multicast of successively refined sources via noisy channels Wireless multicast for media content delivery is expected to support numerous emerging mobile applications, such as mobile IPTV, electronic advertisements, and mobile gaming, due to its one-to-many transmission in nature that is scalable to the number of receivers. Envisioning its importance, the proposed DG program investigates a novel framework of coded wireless multicast, called Scalable source coding over superposition coding (SSC-SPC), which aims to create multi-resolution transmissions via an intelligent mapping between the source and channel coding. Specifically, we plan to tackle the problems of SSC-SPC multicast in a number of interesting scenarios, including a logical SSC-SPC transmission paradigm (called SSC-L-SPC) that enables simple and standard compatible design at the receivers, as well as SSC-SPC multicast over single- and multi-relay networks in the decode-and-forward (DF), amplify-and-forward (AF), non-orthogonal AF (NAF) fashion, respectively. They are considered missing pieces in the literature and interesting to the research community. The research results are expected to gain deep understanding on the performance of the SSC-SPC transmissions under various network infrastructure supports and solidly contribute to the state-of-the-art of the related research. Based on the proposed research topics, the proposed DG program accommodates abundant research activities, by which the participated students, including constantly two PhD students and a summer co-op student, will receive sufficient training in terms of network architecture design, system and problem formulation, optimization, and case studies/simulation. They will not only learn the academic research skills, but also obtain knowledge on industry standardization progress such as Multimedia Broadcast Multicast Services (MBMS) of 3GPP and Multicast-broadcast single-frequency network (MBSFN) in LTE.
