Radomir Stankovic received the B.Sc. degree in electronic engineering from the Faculty of Electronics, University of Ni v, Serbia, Yugoslavia in 1976, and M.Sc. and Ph.D. degrees in applied mathematics from the Faculty of Electrical Engineering, University of Belgrade, Serbia, Yugoslavia, in 1984 and 1986, respectively. Currently, he is a Professor at Department of Computer Science, University of Ni v, Serbia, Yugoslavia. His research interests include spectral techniques, switching theory and multiple-valued logic, and signal processing. He is a member of IEICE. Jaakko Astola (Fellow IEEE) received B.Sc., M.S.c, Licentiate and Ph.D. degrees in mathematics (specializing in error-correcting codes) from Turku University, Finland, in 1972, 1973, 1975, and 1978 respectively. From 1993 he has been Professor of Signal Processing and Director of Tampere International Center for Signal Processing leading a group of about 60 scientists and was nominated Academy Professor by Academy of Finland (2001-2006). His research interests include signal processing, coding theory, spectral techniques and statistics.
