The IEEE Global Conference on Signal and Information Processing (GlobalSIP) is a recently launched flagship conference of the IEEE Signal Processing Society. GlobalSIP' 15 will be held in Orlando, Florida, USA, December 14-16, 201 5. The conference will focus broadly on signal and information processing with an emphasis on up-and-coming signal processing themes. The conference will feature world-class speakers, tutorials, exhibits, and technical sessions consisting of poster or oral presentations.    The Signal Processing in Mobile Multimedia Communication System symposium will focus on the signal processing challenges in delivering real-time multimedia data over wireless links to from servers to mobile devices or between mobile devices. In particular, the symposium will address the signal processing research issues related to seamless delivery of real time multimedia data to mobile devices. The symposium would like to address the following questions. How to design and implement an energy-efficient multimedia coding techniques on battery-operated mobile devices? How could efficiently transmit huge amount of multimedia data between servers and mobile devices? How could best preset multimedia data to mobile devices with limited display size? How to integrate different signal processing techniques that all compete for limited resources, e.g. CPU, memory, battery, display etc., on mobile devices? How to achieve cross-layer optimal resource allocation to maximize the overall quality of service of multimedia services?
