Biography: Robert J. C. Bultitude received the BSc. E.E. degree from the University of New Brunswick in 1975, and the M. Eng., and Ph. D. degrees from Carleton University in 1980 and 1987, respectively, all in electrical/electronics engineering.   He conducted his graduate studies at Carleton as a part time student, while working at The Government of Canada Communications Research Centre (CRC), Ottawa.

Robert worked on mobile radio systems with the consulting firm Hoyles Niblock & Associates (now HN Engineering) in Vancouver from 1975-1977, and on radar head end siting and commissioning with Leigh Instruments, Ottawa during 1979-1980.  In 1980, he joined CRC, where, during the past 34 years, he has conducted both theoretically and experimentally-based research on radio propagation pertinent to portable, indoor, and mobile communications.  From 1989-1999, he managed the CRC Land Mobile and Indoor Radio Propagation Research Group, and in 2000, he relinquished his management position to take up a Research Scientist position in the same group in order to devote more time to research.  After a major reorganisation at CRC in 2012, he was a senior research scientist and senior advisor in a newly formed CRC Radio Propagation Studies Group, until November, 2014. 

Since the early 1990s, Robert has been an Adjunct Research Professor in the Dept. of Systems and Computer Engineering.  During this time he has held an NSERC Discovery Grant, supervised or co-supervised fourteen Master's and Ph.D. students in their thesis work, and led a major Canadian Institute for Telecommunications Research Project, involving professors from Carleton, Laval University and The University of Manitoba.  He also collaborated with Profs. Mahmoud and Falconer and a Ph.D. Student (now Dr. Eliana Yepez) in the implementation of a MIMO channel sounder, which can be made available for use within the department.

Dr. Bultitude was the principal author of a paper that won the IEEE Vehicular Technology Society Neal Shepherd Best Paper award for year 1997, and he is currently an IEEE VTS Distinguished Lecturer.  He is an active participant in the International Radio Science Union (URSI), and in the European COST mobile radio action group.  He also participated in the European WINNER projects.

Summary of Research Interest:  Propagation Measurements & Data Analysis, Channel Modelling (Directional, Double Directional, MIMO), Stochastic Modelling (Temporal and Spatial Change Point and Meta-Analysis), and Digital link performance prediction based on measured data. Frequency Bands: 30 MHz –to-60 GHz.
