  1. 1. Cognitive Radio Networks : Elements and Architectures

    Författare :Alexandru Popescu; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Cognitive radio network management; spectrum access; multiconstrained routing optimization; multi-dimensional adaptation; middleware;

    Sammanfattning : As mobility and computing becomes ever more pervasive in society and business, the non-optimal use of radio resources has created many new challenges for telecommunication operators. Usage patterns of modern wireless handheld devices, such as smartphones and surfboards, have indicated that the signaling traffic generated is many times larger than at a traditional laptop. LÄS MER

  3. 2. Perceive those things which cannot be seen : A cognitive systems engineering perspective on requirements management

    Författare :Åsa Hedenskog; Rune Gustavsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Software tools; Usability requirements; Cognitive systems engineering; Systems engineering; Systemteknik;

    Sammanfattning : Non-functional requirements contribute to the overall quality of software, and should therefore be a part of any development effort. However, in practice they are often considered to be too difficult to handle. The purpose of this thesis is to gain understanding of where the nature and origin of these difficulties may lie.

  4. 3. Increasing the automation of radio network control

    Författare :Åsa Hedenskog; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    Sammanfattning : The efficient utilization of radio frequencies is becoming more important with new technology, new telecom services and a rapidly expanding market. Future systems for radio network management are therefore expected to contain more automation than today's systems.This thesis describes a case study performed at a large European network operator.

  5. 4. Performance Analysis of Cognitive Radio Networks under Spectrum Sharing and Security Constraints

    Författare :Louis Sibomana; Zepernick Hans-Jürgen; Slimane Ben Slimane; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Underlay cognitive radio networks; spectrum sharing constraints; physical layer security;

    Sammanfattning : The cognitive radio network (CRN) concept has been proposed as a solution to the growing demand and underutilization of the radio spectrum. To improve the radio spectrum utilization, CRN technology allows the coexistence of licensed and unlicensed systems over the same spectrum. LÄS MER

  7. 5. On Interference Management With Incomplete Side Information

    Författare :Efthymios Stathakis; Mikael Skoglund; Marios Kountouris; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The evolution towards next generation wireless networks has to serve high expectations and demands, therefore ongoing research has to tackle problems that have hitherto received less attention. A decisive step in this direction is to consolidate cohabitation paradigms into the envisioned communication protocols. LÄS MER
