  1. 21. Towards robust traffic engineering in IP networks

    Författare :Anders Gunnar; Mikael Johansson; Steve Uhlig; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Telecommunication; Telekommunikation;

    Sammanfattning : To deliver a reliable communication service it is essential for the network operator to manage how traffic flows in the network. The paths taken by the traffic is controlled by the routing function. LÄS MER

  3. 22. A flexible framework for detection of feature interactions in telecommunication systems

    Författare :Gustaf Naeser; Bengt Jonsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Systems; Datorteknik;

    Sammanfattning : The complexity of today's telecommunications systems grows with each new feature introduced. As the number of services an operator provides can be used to gain advantage over competitors the number of services will continue to increase. LÄS MER

  4. 23. Peak and Power Reduction in Multicarrier Communication Systems

    Författare :Niklas Andgart; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunikationsteknik; line driver; Signal processing; Signalbehandling; Telecommunication engineering; power reduction; DSL; DMT; tone reservation; PAR; Peak to average ratio;

    Sammanfattning : Broadband multicarrier communication suffers from a large signal span, causing problems in both wireless and wireline systems. This is commonly referred to as a high peak to average ratio (PAR), and leads to a high power consumption, which is an important limitation in many communication systems. LÄS MER

  5. 24. Digital Hardware Aspects of Multiantenna Algorithms

    Författare :Fredrik Edman; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Beamforming; MIMO; FPGA; Implementation; Hardware; Matrix; Inversion; QR-decomposition; SVD; Capon; Signal processing; Signalbehandling; Electronics; Elektronik och elektroteknik; Elektronik; Telecommunication engineering; Telekommunikationsteknik; Electronics and Electrical technology;

    Sammanfattning : The field of wireless communication is growing rapidly, with new requirements for the next generation of mobile and wireless communications technology. In order to achieve the capacities needed for future wireless systems, the design and implementation of advanced communications techniques such as multiantenna systems is required. LÄS MER

  7. 25. Aspects on Interference and Diversity in Wireless Networks

    Författare :Fredrik Florén; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunikationsteknik; Telecommunication engineering; Elektronik och elektroteknik; Electronics and Electrical technology; feedback; multiuser communication; diversity; throughput; packet radio networks; Interference; frequency hop communication;

    Sammanfattning : This thesis deals with two topics in wireless communications: interference between frequency-hopping (FH) networks, and multiuser diversity. The work on FH treats a system where FH is used to provide simultaneous access to the channel for multiple uncoordinated wireless networks. LÄS MER
