  2. 21. Aperiodic Array Synthesis for Telecommunications

    Author : Carlo Bencivenni; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PtP; mutual coupling; SATCOM; compressive sensing; aperiodic array; density taper; MU-MIMO; maximally sparse array; LoS-MIMO;

    Abstract : Arrays of antennas offer important advantages over single-element antennas and are thus a key part of most advanced communication systems. The majority of current arrays are based on a classical regular layout, which offer simple design criteria despite some limitations. READ MORE

  4. 22. Cross-Correlator Implementations Enabling Aperture Synthesis for Geostationary-Based Remote Sensing

    Author : Erik J Ryman; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; full-custom; signal processing; synthetic aperture; Cross-correlation; interferometric imaging; ASIC; remote sensing;

    Abstract : An ever-increasing demand for weather prediction and high climate modelling accuracy drives the need for better atmospheric data collection. These demands include better spatial and temporal coverage of mainly humidity and temperature distributions in the atmosphere. READ MORE

  5. 23. Extending the Bandwidth of the Doherty Power Amplifier

    Author : David Gustafsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The Doherty power amplifier (DPA) is one of the most popular power amplifier (PA) architectures used to obtain high efficiency for modern communication signals having high peak-to-average power ratios. Its often narrowband performance does, however, make it difficult for the DPA to meet the increasing demands of frequency agility in modern wireless communication systems. READ MORE

  6. 24. Design and Implementation of Embedded Video Surveillance Hardware

    Author : Fredrik Kristensen; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektronik och elektroteknik; Electronics and Electrical technology; image features; tracking; labeling; morphology; real-time operations; Hardware design; Image processing; Imaging; image processing; Bildbehandling; Signal processing; Signalbehandling;

    Abstract : The demands on video surveillance systems are rapidly increasing regarding parameters such as frame rate and resolution. Furthermore, with an ever increasing number of video streams, an automated process for extracting relevant information is required. READ MORE

  7. 25. Bio-Inspired Self-Organisation in Evolvable Production Systems

    Author : Dias Ferreira João; Mauro Onori; Luis Ribeiro; José Barata; Niels Lohse; KTH; []
    Keywords : ;

    Abstract : The increasing market fluctuations and customized products demand have dramatically changed the focus of industry towards organizational sustainability and supply chain agility. Such critical changes in the strategic vision of the companies inevitably have a direct impact on the shop-floor operational requirements. READ MORE
