  1. 1. Implementing spectrum commons: Implications for Thailand

    Author : Nattawut Ard-Paru; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spectrum commons; institutional analysis and development IAD framework; spectrum assignment; spectrum allocation; Radio Regulations RR ; World Radiocommunication Conference WRC ; spectrum management;

    Abstract : Spectrum is a natural and limited resource that needs to be managed both internationally and nationally because of the unique propagation characteristics of radio waves. Once transmitted, a radio signal propagates until its power is depleted. Furthermore, electromagnetic energy does not recognize borders between countries. READ MORE

  2. 2. A Software Framework for Prioritized Spectrum Access in Heterogeneous Cognitive Radio Networks

    University dissertation from Karlskrona : Blekinge Institute of Technology

    Author : Yong Yao; Blekinge Tekniska Högskola.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cognitive Radio Networks; Queueing Modelling; Spectrum Decision; Fuzzy-Logic; Cellular Network; Ad-Hoc Network; Mesh Network;

    Abstract : Today, the radio spectrum is rarely fully utilized. This problem is valid in more domains, e.g., time, frequency and geographical location. READ MORE

  3. 3. A Spectrum Decision Support System for Cognitive Radio Networks

    University dissertation from Karlskrona : Blekinge Institute of Technology

    Author : Yong Yao; Blekinge Tekniska Högskola.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Cognitive Radio Networks (CRNs) offer a promising capability of alleviating the problem of spectrum insufficiency. In CRNs, the licensed spectrum channels are either exclusively reserved for licensed users or temporarily used by unlicensed users. The requirement for unlicensed users is to not harmfully impair the licensed users transmissions. READ MORE

  4. 4. On hard-decision forward error correction with application to high-throughput fiber-optic communications
