Poslije predavanja bit će prilike za pitanja i diskusiju te neformalno druženje. Očekivano trajanje cijelog dogadjaja je oko 1,5 sat.
Predavanje će biti na engleskom jeziku.
Sadržaj predavanja:
Ultra-wide bandwidth (UWB) wireless is envisioned as a license-free replacement for cables and wires, able to transmit at extremely high data rates over short distances and has been dubbed “Bluetooth on steroids”. The principles and structures of time-hopping (TH)
ultra-wide bandwidth (UWB) wireless systems are recalled and the
suitability of the conventional matched filter (correlator) digital
receiver for TH-UWB applications is discussed. Insights into the
performance of the matched filter TH-UWB receiver is gained from study
of examples of the simulated probability density function of the TH-UWB
multiple access interference. Some new TH-UWB receiver designs are
proposed based on examining the characteristics of the simulated
multi-user interference density functions. Soft-limiting and zonal
receiver structures are intuitively motivated and shown to outperform
the conventional matched filter UWB receiver by many dB's in
signal-to-noise ratio (SNR). A p-order metric receiver is also proposed
and its superior performance established. The improved receiver
performances are explained using maximum likelihood (ML) receiver design
principles. The application of the new signal detection structures in
modified Rake receiver designs for multipath fading UWB channels is
explored. Recent preliminary results for an UWB receiver currently
under study that is based on an alpha-stable interference model will
also be presented.

Norm Beaulieu received the B.A.Sc. degree, the M.A.Sc. degree and the
Ph.D. degree, all in electrical engineering from the University of
British Columbia in Canada. He also studied at McGill University and
the Technical University of Denmark. Professor Beaulieu was appointed
Queen’s National Scholar Assistant Professor at Queen’s University, and
subsequently Associate Professor and Full Professor at Queen’s. Dr.
Beaulieu now holds two research chairs at the University of Alberta, the
iCORE Research Chair in Broadband Wireless Communications and the Canada
Research Chair in Broadband Wireless Communications. Dr. Beaulieu is the
recipient of the J Gordin Kaplan Award for Excellence in Research of the
University of Alberta, the Royal Society of Canada Thomas W. Eadie
Medal, “in recognition of major contributions to Engineering or Applied
Science”, and the Engineering Institute of Canada Médaille K.Y. Lo
Medal, “for significant engineering contributions at the international
level”. Professor Beaulieu served as the Editor-in-Chief of the IEEE
Transactions on Communications, in the period January 2000 to December
2003. He is a Fellow of The Royal Society of Canada, a NSERC E.W.R.
Steacie Memorial Fellow, a Fellow of the Institute of Electrical and
Electronics Engineers (IEEE), a Fellow of the Engineering Institute of
Canada (EIC), and a Fellow of the Canadian Academy of Engineering.
