  2. 1. Radio resource management for wireless indoor communication systems : performance and implementation aspects

    Author : Stefan Pettersson; KTH; []
    Keywords : Radio resource management; indoor communication; the bunch concept; centralized RRM; dynamic channel allocation; channel selection;

    Abstract : In this thesis, we investigate several radio resourcemanagement (RRM) techniques and concepts in an indoorenvironment with a dense infrastructure. Future wireless indoorcommunication networks will very likely be implemented atplaces where the user concentration is very high. At these hotspots, the radio resources must be used efficiently.

  5. 3. Radio Resource Management in Bunched Personal Communication Systems

    Author : Miguel Berg; KTH; []
    Keywords : radio resource management; dynamic channel allocation; power control; interference avoidance; link-gain matrix; path-loss measurements; microcells; mobile positioning; trilateration;

    Abstract : The traditional way of increasing capacity in a wirelesscommunication system has been cell splitting and fixedchannel-allocation based on prediction tools. However, theplanning complexity increases rapidly with the number of cellsand the method is not suitable for the large temporal andspatial traffic variations expected in the future. READ MORE

  6. 4. On Dynamic Spectrum Access in Cognitive Radio Networking

    Author : Said Rutabayiro Ngoga; Blekinge Tekniska Högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cognitive Radio; Cognitive Radio Networking; Dynamic Spectrum Access; Wireless Communications;

    Abstract : The exploding increase of wireless communications combined with the existing inefficient usage of the licensed spectrum gives a strong impetus to the development and standardization of cognitive radio networking and communications. In this dissertation, a framework for Dynamic Spectrum Access (DSA) is first presented, which is the enabling technology for increasing the spectral efficiency of wireless communications. READ MORE

  7. 5. Relaying Protocols for Wireless Networks

    Author : Majid Nasiri Khormuji; Erik G. Larsson; Christian Ibars; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; The relay channel; constellation rearrangement; decode-and-forward; resource allocation; Telecommunication theory; Telekommunikationsteori;

    Abstract : Motivated by current applications in multihop transmission and ad hoc networks, the classical three-node relay channel consisting of a source-destination pair and a relay has received significant attention. One of the crucial aspects of the relay channel is the design of proper relaying protocols, i.e. READ MORE
