The online venue is located in the campus and facility of the Faculty This year’s edition of the Microwave and Radio of Electrical Engineering and Communication, 3 Electronics Week 2021 (MAREW 2021) consists Brno University of Technology. of two traditional conventions – The 31st International Conference RADIOELEKTRONIKA I would like to thank all above mentioned 2021 and The 20th Conference on Microwave partners for a good cooperation and also for Techniques COMITE 2021. the technical and financial support. Thanks to TPC members, local committee and organizers The purpose of the three day event of the for their excellent work. Many thanks also to MAREW 2021 is to create a discussion forum for our sponsors. Special thanks are aimed to our researchers, academics, people in industry, and colleagues at University of Pardubice for the students who are interested in the latest research web pages and in-house conference system and development in the area of electronics, that have been used very effectively but again signal processing and applications, information improved this year. technologies, microwave techniques and related disciplines. The detailed program is scheduled to several plenary and conference sessions on next pages. We have prepared interesting online plenary I hope you will find MAREW 2021 inspiring and sessions from respected university professors you will spend your time on listening interesting and academia speakers on visionary topics. talks and discussing seriously all your related In advance, professionals from industry will questions. In the meantime, please feel also also speak in the plenary about the future and mutual synergy between academia and industry, challenging trends in the radio electronics and sharing of knowledge and social aspects of our microwave techniques. meeting and event in general. The technical program and plenary talks are Welcome and enjoy your online time with us. organized by the Department of Radio Electronics, Brno University of Technology in cooperation with Czech and Slovak technical universities and also under auspices of the IEEE Czechoslovakia Section, U.R.S.I., Radioengineering Society and Tomas Kratochvil General Chair www.marew.cz MAREW 2021 COMMITTEES Guarantors: Local Committee: Brancik Lubomir 4 Brno University of Technology (CZ) University of Pardubice (CZ) Brno University of Technology (CZ) Slovak University of Technology in Bratislava (SK) Hudcova Lucie Czech Technical University in Prague (CZ) Brno University of Technology (CZ) Technical University of Kosice (SK) Lacik Jaroslav Brno University of Technology (CZ) General Chair: Marsalek Roman Kratochvil Tomas Brno University of Technology (CZ) Brno University of Technology (CZ) Petrzela Jiri Brno University of Technology (CZ) TPC Chair: Polak Ladislav Brno University of Technology (CZ) Raida Zbynek Pomenkova Jitka Brno University of Technology (CZ) Brno University of Technology (CZ) Publication Chair: Povalac Ales Brno University of Technology (CZ) Fryza Tomas Prokes Ales Brno University of Technology (CZ) Brno University of Technology (CZ) Raida Zbynek Conference Treasurer: Brno University of Technology (CZ) Sigmund Milan Lucie Hudcova Brno University of Technology (CZ) Brno University of Technology (CZ) Sotner Roman Brno University of Technology (CZ) MAREW 2021 Program MAREW 2021 COMMITTEES RADIOELEKTRONIKA Committee: Sigmund Milan, Brno Univ. of Technology (CZ) Sotner Roman, Brno Univ. of Technology (CZ) Baudoin Genevieve, ESIEE Paris (FR) Stofanik Vladimir, STU Bratislava (SK) Balkovic Mislav, Visoka Skola za Primijenjeno 5 Suhartanto Heru, University of Indonesia (IN) Racunarstvo (HR) Tekovic Alberto, Access Network Engineering Biolek Dalibor, Univ. of Defence in Brno (CZ) (HR) Brancik Lubomir, Brno Univ. of Technology (CZ) Trivedi Gaurav, IIT Guwahati (IND) Djambic Goran, Visoka Skola za Primijenjeno Ulovec Karel, Czech Technical University in Racunarstvo (HR) Prague (CZ) Dobes Josef, Czech Technical University in Prague (CZ) Drutarovsky Milos, Technical University of COMITE Committee: Kosice (SK) Fliegel Karel, Czech Technical University in Prague Balling Peter, Antenna System Consulting (DK) (CZ) Bartolic Juraj, University of Zagreb (HR) Galajda Pavol, Technical Univ. of Kosice (SK) Bezousek Pavel, Univerzity of Pardubice (CZ) Hagara Miroslav, STU Bratislava (SK) Bozzi Maurizio, University of Pavia (I) Hribik Jan, STU Bratislava (SK) Cocherova Elena, STU Bratislava (SK) Juhar Jozef, Technical Univ. of Kosice (SK) Filip Ales, AZD Prague, LIS (CZ) Kocur Dusan, Technical Univ. of Kosice (SK) Fiser Ondrej, AV CR Prague, (CZ) Kolka Zdenek, Brno Univ. of Technology (CZ) Hudcova Lucie, Brno Univ. of Technology (CZ) Kratochvil Tomas, Brno Univ. of Technology (CZ) Kasal Miroslav, Brno Univ. of Technology (CZ) Laurent Simon, Universite du Maine (FR) Lacik Jaroslav, Brno Univ. of Technology (CZ) Leite Vicente, Politéchnico de Braganca (PTG) Lima Rodolfo, Brazilian Navy Research Institute Marsalek Roman, Brno Univ. of Technology (CZ) (BR) Mishra Amit Kumar, Univ. of Capetown (JAR) Luxey Cyril, University of Nice-Sophia Antipolis (FR) Moric Zlatan, Visoka Skola za Primijenjeno Racunarstvo (HR) Machac Jan, Czech Technical University in Prague (CZ) Nemec Zdenek, University of Pardubice (CZ) Ovsenik Lubos, Technical Univ. of Kosice (SK) Ondas Stanislav, Technical Univ. of Kosice (SK) Pechac Pavel, Czech Technical University in Ondracek Oldrich, STU Bratislava (SK) Prague (CZ) Petrzela Jiri, Brno Univ. of Technology (CZ) Polivka Milan, Czech Technical University in Pidanic Jan, University of Pardubice (CZ) Prague (CZ) Pleva Matus, Technical Univ. of Kosice (SK) Raida Zbynek, Brno Univ. of Technology (CZ) Plsek Radek, Era, a.s.

Pareto modelling is ETEL (Cuba) realized for quantifying the trade-off among three Key Performance Indicators (KPIs): power consumption, Multi-Objective Optimization of Dynamic Spectrum spectrum utilization, and global network exposure. Instead Access Networks of the traditional distributed architecture for the spectrum management, a cloud-based architecture is considered Abstract: The lack of spectrum availability for satisfying in our network planning. Compared to the traditional the exponential increase in wireless services demand cognitive radio network, the proposed architecture and has become an important concern in the wireless optimization algorithm reduced the network power communication community. Paradoxically, several consumption by 27.5%, the average network global spectrum measurements campaigns have demonstrated exposure by 34.3%, and spectrum utilization by 34.5% for that most of the spectrum is not in use or is sub-utilized. the best trade-off among the three KPIs. The interference These surveys for different spectrum bands show that less to the primary service is also reduced at least by 27% in than 20% of the spectrum is used at any given location rural and suburban areas. The centralized architecture also and instant of time. The allocation of spectrum at higher allows the coexistence of heterogeneous networks with frequency bands has a significant impact on the network different physical and medium access control layers, as the investment and operational cost compared to the same information exchange occurs in a higher layer. technological solution at lower spectrum bands. The improvement of technologies’ spectral efficiency has helped to cope
