  3. 2. Exploiting the Direct Communication Link for Enhancing Effective Capacity Performance of Cognitive Radio Relay Networks

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Md Abdul Matin Biswas; [2014]
    Keywords : Cognitive Radio; Quality of Service QoS ; Effective Capacity; Cooperative Relaying; Cognitive Relay Networks; Peak Interference Power Constraint; Delay QoS Constraint;

    Abstract : Nowadays, cognitive radio (CR) is a promising concept to improve the radio spectrum exploitation. CR has tremendous ability to enhance spectrum efficiency by allowing secondary users (SUs) to access licensed radio spectrum resource which is currently not being used by primary users (PUs).

  4. 3. The Performance of Dual-Hop Decode-and-Forward Underlay Cognitive Relay Networks with Interference Power Constraints over Weibull Fading Channels

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Andawattage Chaminda Janaka Samarasekera; [2014]
    Keywords : Cognitive Radio; Weibull Fading Channels; Cooperative Communication; Cognitive Relay Networks;

    Abstract : With the rapid development and the increasing use of wireless devices, spectrum scarcity has become a problem. The higher frequencies have bad propagation characteristics and the lower frequencies have low data rates, therefore the radio spectrum that is available for efficient wireless transmission is a limited resource.
