Title: Cooperative Communication-An Overview
Speaker: Behnaam Aazhang (9:10-9:50)

ABSTRACT

Within the last five years, there has been a cultural shift from wired landlocked connectivity to pervasive wireless information access. Most emerging mobile devices are now equipped with some form of embedded wireless radio. The expectations of high data rates and increased battery longevity have put tremendous pressure on all aspects of wireless system design. To meet the challenges of next generation wireless system design, we need fundamentally new methods to exploit all available dimensions of communication channels and network.

In this presentation, I will talk about emerging systems and network level techniques to increase spectral and power efficiency of communication systems, and extend coverage of wireless networks. The cooperative communication paradigm pools distributed resources of different nodes, such that the nodes act like a collaborative system instead of greedy adversarial participants. I will present our research and development plans in the context of a scalable experimental wireless system for mobile broadband Internet.
