It is not yet completely clear how 4G wireless systems will look like, but so far "4G" has been used as an umbrella term for a number of recent advances in wireless communications. One of those advances is the cognitive radio concept, where devices will look for holes in the spectrum (a.k.a. spectrum sensing) and dynamically share the free spectrum with other devices (a.k.a. dynamic resource allocation). Combining these ideas with the use of multiple antennas per device opens up another dimension. This extra degree of freedom leads to improved performance, but it complicates the required signal processing algorithms. We feel that it is time to join all these research efforts in a thematic symposium on 4G, which will be of interest to industry as well as to students active in this research area.
Each talk is 40 minutes long.

There is growing interest in network distributed signal processing algorithms and applications, such as distributed environmental sensing, detection and estimation, filtering, adaptive networks, learning, motion estimation and scene analysis, to name a few. Beyond local computation, network distributed signal processing algorithms must also take into account the constraints and opportunities in the underlying communication network (e.g., time-varying link capacities, battery power, etc). Whereas most current research in the area is focused on sensor networks, there are emerging applications that will operate over hybrid heterogeneous networks. This symposium includes tutorials and sessions that cover recent developments in network distributed signal processing, filtering, estimation, and adaptation.
Each talk is 40 minutes long.

With the advent of modern communication technology, physical distance is no longer a barrier to real-time interaction. But current technologies are not perfect: cellular networks typically lack a video component; broadband connections hardly provide for an immersive experience; high-end remote presence solutions are expensive and constraining. Therefore there is a strong need of research and development of advanced technologies and tools to bring immersive experience into teleconferencing so people across geographically distributed sites can interact collaboratively. This requires deep understanding of multiple disciplines. The Immersive Communication TS touches the topics of user experience, speech processing, 3D video, and multi-modal processing.
Each talk is 40 minutes long.

Although information retrieval is a mature area for text documents, search and retrieval of audio and visual sources is still in its infancy. Multimedia search and retrieval is a hot research area whose aim is to handle the explosion of speech, language, sound, image and video data in modern communication and storage systems. In this symposium, we highlight the latest research advances and industrial developments in search and retrieval of multimedia information.
Each talk is 40 minutes long.
