Abstract
Ultra - Wideband (UWB) is an imerging radio technology that has
received much attention recently. Contrary to traditional radio systems
that use a sinusoidal carrier, UWB uses a pulsed carrier which implies a
wide instantaneous bandwidth. The inherent wide band nature of UWB signals
suggests that the technology could find use in a number of applications
involving radar, communications, position determination, and through - material
imaging. UWB radio architectures also offer reduced complexity, size
and cost. Presented will be an overview of the technology as well as
research recently conducted in this field by the Center for Ultra - Wide band
Research and Engineering at Applied Research Laboratories. This work includes
both a study of the effects of UWB emissions on Global Positioning System (GPS)
receivers as well as UWB antenna design. The initial findings of these two
research efforts will be discussed.
Biography
Aaron Kerkhoff is a research scientist at Applied Research Laboratories
at the University of Texas - Austin. He received Bachelor of Science
degrees in Electrical and Computer Engineering from the University of Missouri
- Columbia in 1998. He is currently pursuing a Master of Science degree
in Electrical Engineering from the University of Texas - Austin. His Master's
thesis involves the use of the Genetic Algorithm approach in the design of
Ultra - Wideband antennas.
Douglas A. Cummings holds an MBA in Technology Management from the
University of Phoenix and a BS in Electrical Engineering from Arizona
State University. His professional career includes more than 8 years of
telecommunications experience to include the design, installation, and
evaluation of CDMA based cellular systems, as well as systems
integration and test experience on the Iridium satellite communications system.
He is currently the Coordinator of the Center for Ultra Wideband Research and
Engineering (CURE) and a member of the Advanced Systems Division of the
Applied Research Laboratories.
