  2. 1. Studies of Three Different Methods to Estimate the Up-link Performance of Mobile Phone Antennas

    Author : Sathyaveer Prasad; Peter Händel; Claes Beckman; Jan Carlsson; Högskolan i Gävle; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Antenna measurements; mobile phones; total radiated power; reverberation chamber; anechoic chamber; Telia Scattered Field Method; Maximum likelihood Estimator; Telecommunication; Telekommunikation;

    Abstract : Antennas play an important role in determining the overall radio performance for wireless communications. If all other radio components perform according to their specifications, the performance of a mobile phone can be entirely determined by measuring the efficiency of its antenna. READ MORE

  4. 2. Accounting, Stock Markets and Everyday Life

    Author : Gustav Johed; Jan-Erik Gröjer; Bino Catasús; David Cooper; Uppsala universitet; []
    Keywords : Business studies; Accounting; Actor Network Theory; Annual General Meetings; Private Investors; Sociology of Translation; Företagsekonomi;

    Abstract : The backdrop of this dissertation is one ubiquitous element of everyday life: the stock market. Traditionally, accounting and stock markets are logically coordinate entities and this thesis analyzes how accounting supports private investors in their role as shareholders – as investors in shares and owners of companies.

  5. 3. Synchronization for Multicarrier Systems

    Author : Daniel Landström; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; Signalbehandling; Frequency estimation; Time estimation; Maximum-Likelihood; Synchronization; OFDM; DMT;

    Abstract : This thesis has synchronization of Multicarrier systems, more specifically Orthogonal Frequency Division Multiplexing (OFDM) systems, as the main theme. The thesis addresses two areas, the first proposing and analyzing time and frequency estimators for OFDM systems, the second investigating more practical issues around these estimators. READ MORE

  6. 4. Strategic Management of Resource Allocation to Applied Research – Towards a Holistic Approach

    Author : Fredrik Hörstedt; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; applied research; telecommunication; resource allocation; strategic technology management;

    Abstract : This thesis is concerned with the strategic management of applied research in companies, i.e. the operations close to the R in a companys R&D (Research and Development) operations. READ MORE

  7. 5. Hilbert space frames and bases : a comparison of Gabor and wavelet frames and applications to multicarrier digital communications

    Author : Niklas Grip; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Abstract : Several signal processing applications today are based on the use of different transforms. The signals under consideration are written as a linear combination (or series) of some predefined set of functions. Traditionally, orthogonal bases have been used for this purpose, for example, in the discrete Fourier transform. READ MORE
