Octavia A. Dobre

Memorial University, Canada



In a world of rapid growth of commercial wireless services, accommodating the explosive demand for spectrum access, efficiency, and reliability becomes increasingly technically challenging. A solution is provided by flexible cognitive and intelligent radios, which sense the environment and respond intelligently, without explicit pre-configuration to define their functions. Additionally, implementation of advanced information services for military applications in a crowded electromagnetic spectrum is a challenging task. Friendly signals should be securely transmitted and received, whereas hostile signals must be located, identified, and jammed. Advanced techniques for real-time signal intelligence are required, which has created the need for flexible cognitive and intelligent radio systems. This talk focuses on blind signal classification —an important task of cognitive and intelligent radios.— In particular, a cyclostationarity-based approach to space time block code classification will be presented. Additionally, the talk will outline new and challenging problems in the dynamic research field of signal classification.



Octavia A. Dobre received the Dipl. Ing. and Ph. D. degrees in ECE from the Polytechnic University of Bucharest (formerly the Polytechnic Institute of Bucharest), Romania, in 1991 and 2000, respectively. In 2001 she held a Fulbright fellowship at Stevens Institute of Technology, USA. Between 2002 and 2005, she was a Research Associate with New Jersey Institute of Technology, USA. Since 2005 she has been with the Faculty of Engineering and Applied Science at Memorial University, Canada, where she is currently an Associate Professor.

Her research interests include cognitive radio systems, spectrum sensing techniques, blind signal recognition and parameter estimation techniques, transceiver optimization algorithms, dynamic spectrum access, cooperative wireless communications, network coding, and resource allocation. Dr. Dobre published over 100 journal and conference papers in these areas. Her research has been funded by NSERC, CFI, MITACS, DRDC, CRC, DTA Systems, Agilent, Altera, Keithely Instruments, KOSEF, and RDECOM.

Dr. Dobre is an Editor for the IEEE Communications Letters, IEEE Communications Surveys and Tutorials, and ELSEVIER PHYCOM, and served as a Guest Editor for the IEEE Journal of Selected Topics on Signal Processing and Lead Guest Editor of the ELSEVIER PHYCOM "Cognitive Radio: The Road for its Second Decade" special issue.

She currently serves as the Co-Chair for the IEEE ICC 2013 and IEEE GLOBECOM 2013 (Signal Processing for Communications Symposium), and IEEE VTC Spring 2013 (Multiple Antenna Systems and Services Track). She was the technical program Co-Chair for the IEEE CCECE 2009 (Signal Processing and Multimedia Symposium) and ICNC 2012 (Signal Processing for Communications Symposium).
