Abstract:The increase of capacity to support orders of magnitude increase in data rates of a wireless network in a heavily user congested area with little available spectrum is one of the toughest problems facing the network community.  Traditional information and communication theory methods provide only modest gains and no such techniques suggest any prospect of substantial increase in user rates.  This talk describes a novel architecture that is enabled by broadband fiber networks in the local area, multiple antenna techniques and the availability of massive computing capability at low costs for processing. We propose a novel wireless processing center (WPC) and novel network techniques that combines the functions performed by base stations and switching centers in current wireless system architectures. We believe this WPC architecture will provides orders of magnitude increase in user data rate over current designs of micro and nano cells.
Short Bio:
Vincent W. S. Chan, the Joan and Irwin Jacobs Professor of EECS, MIT, received his BS(71), MS(71), EE(72), and Ph.D.(74) degrees in EE all from MIT. From 1974 to 1977, he was an assistant professor, EE, at Cornell University. He joined MIT Lincoln Laboratory in 1977 and had been Division Head of the Communications and Information Technology Division until becoming the Director of the Laboratory for Information and Decision Systems (1999-2007). He is currently a member of the Claude E. Shannon Communication and Network Group at the Research Laboratory of Electronics of MIT.In July 1983, he initiated the Laser Intersatellite Transmission Experiment Program and in 1997, the follow-on GeoLITE Program. In 1989, he formed the All-Optical-Network Consortium among MIT, AT&T and DEC.  He also formed and served as PI the Next Generation Internet Consortium, ONRAMP among AT&T, Cabletron, MIT, Nortel and JDS, and a Satellite Networking Research Consortium formed between MIT, Motorola, Teledesic and Globalstar. He has founded in 2009 and is serving as the Editor-in-Chief of a new IEEE/OSA Journal: Journal of Optical Communications and Networking. He is currently a Member of the
Corporation of Draper Laboratory, the Technical Advisory Board of Mercury Computer and on the Board of Governors of the IEEE Communication Society. He is also an elected member of Eta-Kappa-Nu, Tau-Beta-Pi and Sigma-Xi, the Fellow of the IEEE and the Optical Society of America.Throughout his career, Professor Chan has spent his research focus on communication and networks, particularly on free space and fiber optical communication and networks and satellite communications. His work has led the way to a successful laser communication demonstration in space and early deployment of WDM optical networks. His recent research emphasis is on heterogeneous (satcom, wireless and fiber) network architectures with stringent performance demands

Abstract: Ultimate goal of wireless technology is to provide high quality gigabit data services under limited available wireless bandwidth and signal power. The wireless channel is severely frequency-selective. Frequency-domain wireless signal processing and multi-input/multi-output transmission (MIMO) techniques may play an important role in significantly increasing the data rate in such a frequency-selective channel. However, using these techniques only is not sufficient. If the present network architecture is employed, the presence of the co-channel interference (CCI) limits the frequency utilization and gigabit data services need prohibitively high transmit power. A new wireless network that can significantly reduce the transmit power and hence reduce the CCI is required. An introduction of distributed antenna network (DAN) architecture is a promising solution to significantly increase the data rate while keeping the communication quality. In this talk, we will overview the recent advance in DAN using distributed frequency-domain MIMO signal processing.
