  1. 1. Applications of Resource Optimization in Wireless Networks

    Author : Patrik Björklund; Peter Värbrand; Mikael Johansson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimization; telecommunication; scheduling; gsm; wcdma; ad-hoc; frequency planning; Telecommunication; Telekommunikation;

    Abstract : The demand for wireless communications is increasing every year, but the available resources are not increasing at the same rate. It is very important that the radio resources are used in an efficient way allowing the networks to support as many users as possible. READ MORE

  2. 2. Interference Rejection and Channel Detection in Mobile Communication

    Author : Fredrik Nordström; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; detection of abrupt changes; WCDMA; Viterbi decoder; Kalman filter; co-channel interference; TDMA; EDGE; Mathematics; Matematik;

    Abstract : This thesis is devoted to statistical problems in mobile communication, in particular disturbance rejection and change detection are studied. Co-channel interference is a significant problem for systems based on TDMA, e.g. EDGE. READ MORE

  3. 3. The development of wireless infrastructure standards

    Author : Fredrik Gessler; KTH; []
    Keywords : standards; standardisation; wireless communication; technologocial development; development process; DECT; WCDMA; 3G;

    Abstract : This thesis treats the development of wirelessinfrastructure standards resulting from co-operative research,development and standardisation efforts. It strives to identifykey influences on this development process, and toconceptualise the process itself. READ MORE

  4. 4. Design of superconductor digital circuits for a 30 GHz DSP and for interface to qubits

    Author : Samuel Intiso; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VHDL; thermal; RSFQ; noise temperature; Time-delay Optimization; WCDMA; Hierarchycal memory; DSP;

    Abstract : Superconducting digital technology based on Rapid Single Flux Quantum logic (RSFQ) is a digital technology characterized by high speed, low power consumption and low operational temperatures. RSFQ is attractive for many applications and in particular for high frequency Digital Signal Processing (DSP) and for digital control of mK devices like superconducting qubits. READ MORE

  5. 5. Aspects of Fixed-point Implementation of Multiuser Detctors in WCDMA

    Author : Hongxia Zhao; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Wideband code-division multiple-access (WCDMA) has been selected as the radio technique standard for the 3G mobile communication systems. However, it is well known that the conventional single-user detector, which is commonly used in CDMA systems, suffers from multiple-access interference (MAI). READ MORE
