PM8: SDE Concept: A Revolutionary New Approach for Researching, Building and Teaching of ICT Systems

Géza Kolumbán, Pázmány Péter Catholic University & Edith Cowan University

Abstract: Band-pass signals are used everywhere in Information and Communications Technology (ICT) and measurement engineering. Many biomedical applications also rely on band-pass signals. The band-pass property makes the substitution of these RF/microwave/optical/biological analog signal processing tasks possible with a low-frequency digital one in Software Defined Electronics (SDE). In SDE, the high frequency band-pass signals are transformed into the BaseBand (BB) by a universal HW device and every application is implemented in BB, entirely in software. SDE concept (i) assures the use of the lowest sampling rate attainable theoretically and (ii) uses the same universal HW device/platform in every application. Key feature of SDE concept is that information is neither lost nor distorted during the transformation. The SDE systems are implemented as embedded computing frameworks where the system level design relies on the layered structure of OSI BR conceptual model. The huge level of flexibility offered by the SW implementation and embedded operation is essential in scientific research and in many applications from cognitive radio to adaptive reconfigurable systems. Because every application is implemented in SW, the gap between research and mass production can be reduced, even eliminated, and the time-to-market can be shortened. Last but not least the SW implementation enables the reconfiguration of an already installed application by changing its SW. The tutorial will survey the SDE theory, propose a step-by-step approach for the derivation of BB equivalents and demonstrate the use of SDE concept in scientific research, university education and prototyping.


Géza Kolumbán

He (FIEEE’05) received his M.Sc. (1976) and Ph.D. (1990) degrees from the Technical University of Budapest, C.Sc. (1990) and D.Sc. (2004) degrees from the Hungarian Academy of Sciences, and Dr.habil degree (2005) from the Budapest University of Technology and Economics. After his graduation, he spent 15 years in professional telecommunications industry, where he developed frequency synthesizers and participated in many system engineering projects from satellite telecommunications to digital radio communications. After joining the university education he has shown that chaos exists in autonomous analog phase-locked loops, elaborated the theory of chaotic waveform communications and established noncoherent chaotic communications as a brand new research direction. He developed DCSK and FM-DCSK, the most popular chaotic modulation schemes. Two of his papers have been ranked in top-cited IEEE Trans. CAS-I articles. He has been a visiting professor and researcher to UC Berkeley, PolyU and CityU in Hong Kong, University College Dublin and Cork, Ireland, EPFL, Lausanne, Switzerland, INSA-LATTIS Laboratory, Toulouse, France, TU Dresden, Germany, Beijing Jiaotong University, China. He has been providing consulting service for many companies from National Instruments to Samsung Advanced Institute of Technology. He is currently a professor at the Faculty of Information Engineering and Bionics, Pázmány Péter Catholic University, Budapest, Hungary and is an Adjunct Prof. at the School of Engineering, Edith Cowan University, Perth, Australia. Prof. Kolumbán was awarded the IEEE Fellowship in 2005 for his contributions to the theory of “double sampled phase-locked loops and noncoherent chaotic communications’.’ He served as an IEEE CAS Distinguished Lecturer for the time period of 2013-2014. He was on the Editorial Board of Elsevier DSP Journal and serves as an Assoc. Editor of the IEEE TCAS-II and Dynamics of Continuous, Discrete and Impulsive Systems, Series B (DCDIS-B).
