ABSTRACT:
Space-time communication systems have better performance in the presence of a rich multipath environment, in which the diversity produced by the multipath allows both space and time to be used to maximize the performance. The size of a room will influence the performance. For a given room size, in order to efficiently use the available wireless spectrum over space and time, there will be a vague minimum required wireless bandwidth threshold above which one should use in order to minimize the harmful effects of spatial correlation on a multiple-input multiple-output (MIMO) multiuser communication system. Allocating spectrum below this threshold may be inefficient over space and time. In nearly line-of-sight channels, maximizing the performance requires that the access points be separated on the order of a symbol wavelength.
BIO:
Brent Petersen received the Ph.D. at Carleton University in Ottawa, Canada, in 1992. He held a post-doctoral fellowship at the IBM Zurich Research Laboratory from 1992 to 93. From 1994 to 97 he was at the University of Calgary and TRLabs. Finally, in 1997, he joined the Department of Electrical and Computer Engineering, at the University of New Brunswick. He is an Associate Professor and a Senior Member of the IEEE. In 2006, he co-authored the paper, titled "Symbol-wavelength MMSE gain in a multi-antenna UWB system", which received the Communications Networks and Services Conference (CNSR) 2006 Best Paper Award.
