    Sammanfattning : With the growing popularity of integrating mobile networks and social networks, people now enjoy a freer and more efficient means of communication. Smarter mobile devices facilitate modern human life. In the information age, various new types of information have begun to appear. LÄS MER

  3. 17. Delay-Stability of Power Control in Wireless Networks

    L3-uppsats, KTH/Reglerteknik

    Författare :Benjamin Heinrich; [2011]
    Nyckelord :;

    Sammanfattning : In this thesis, we investigate the stability of uplink power control algorithms in wireless networks. We derive an abstract block-diagram model of the power-control loop similar to the model in [6]. LÄS MER

  4. 18. Temporal and Spatial Interference Correlations in Cognitive Radio Networks with Vertical Cooperation

    Master-uppsats, KTH/Kommunikationsnät

    Författare :Akis Merve; [2011]
    Nyckelord :Cognitive radio network; vertical cooperation; temporal correlation; spatial correlation;

    Sammanfattning : Cognitive radio technology provides a solution for the spectrum scarcity issue by allowing the unlicensed users which are the cognitive radio devices to share the licensed band with the licensed (primary) users. The abilities of cognitive radio device help the secondary (unlicensed) nodes to observe the licensed band and to adjust their transmission parameters for maintaining the primary communication since in cognitive radio networks, it is essential that the existence of the unlicensed users must not harm the licensed network.

  5. 19. Hybrid Power Control in Time Division Scheduling Wideband Code Division Multiplex Access

    Master-uppsats, KTH/Kommunikationssystem, CoS

    Författare :Zhuo Cheng; [2011]
    Nyckelord :WCDMA; High-Speed Uplink Packet Access; Power Control; unused code GRAKE;

    Sammanfattning : With high date rates using Enhanced Uplink (EUL), a conventional signal to interference ratio (SIR) based power control algorithm may lead to a power rush due to self interference or incompatible SIR target [2]. Time division (TD) scheduling in Wideband Code Division Multiplex Access (WCDMA) is considered to be a key feature in achieving high user data rates. LÄS MER
