  2. 1. Modeling, Implementation and Evaluation of IP Network Bandwidth Measurement Methods

    Author : Andreas Johnsson; Mats Björkman; Bob Melander; Gábor Vattay; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer networks; Bandwidth measurement; Wireless networks; Computer science; Datavetenskap; Datavetenskap;

    Abstract : Internet has gained much popularity among the public since the mid 1990's and is now an integrated part of our society. A large range of high-speedbroadband providers and the development of new and more efficient Internet applications increase the possibilities to watch movies and live TV, use IP-telephony and share files over the Internet.

  4. 2. On Performance of Digital Radio Receiver in Non-Gaussian Interference

    Author : Kia Wiklundh; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bandwidth conversion; performance estimation; APD; interference; minimum shift keying; man-made noise; Gaussian approximation; measurement; emission requirements; non-Gaussian interference; micro-wave oven; MSK; amplitude probability distribution; emission;

    Abstract : Interference from electrical equipment can degrade a co-located digital radio receiver severely. To avoid this performance degradation it is necessary to have estimation methods to predict the influence from an interference environment on a radio receiver in advance. READ MORE

  6. 4. Design of Functional Structures and Measurement Techniques for Electromagnetic Waves

    Author : Johan Lundgren; Teoretisk elektroteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; functional structures; frequency selective structures; polarization selectivity; metasurface; near-field measurements; antenna measurements; scattering measurement; power density; random media;

    Abstract : Electromagnetic fields exist all around us. Through evolution, nature has developed tools to interact and use these fields, where our eyes are a spectacular example. Humans have a long history of developing structures and objects of their own to alter and interact with these fields. READ MORE

  7. 5. Design Aspects of Fully Integrated Multiband Multistandard Front-End Receivers

    Author : Adiseno; KTH; []
    Keywords : low-noise amplifier; mixer; RF front-end; wireless receiver; noise figure; linearity; bandwidth; dual-loop feedback;

    Abstract : In this thesis, design aspects of fully integrated multibandmultistandard front-end receivers are investigated based onthree fundamental aspects: noise, linearity and operatingfrequency. System level studies were carried out to investigatethe effects of different modulation techniques, duplexing andmultiple access methods on the noise, linearity and selectivityperformance of the circuit.
