  1. 1. Performance Analysis of a Cooperative Communication Network Over κ - μ Shadowed Fading for Different Relaying Protocols

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Alekhya Kodide; [2016]
    Keywords : Cooperative communications; κ−µ shadowed fading; relaying protocols; outage probability;

    Abstract : With the fast development of today’s multimedia services, engineers face a huge hurdle that is, the overwhelming need of highly reliable communication over long distances. Cooperative communication is a novel concept which tackles this problem effectively. READ MORE

  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. Spectrum Selection Technique to Satisfy the QoS Requirements in Cognitive Radio Network

    University essay from Blekinge Tekniska Högskola/Sektionen för datavetenskap och kommunikation

    Author : Sheikh Fakhar Uddin; Ismail Khan Khattak; [2012]
    Keywords : Cognitive Radio Network; QoS; Spectrum Selection ;

    Abstract : The demand of wireless spectrum is increasing very fast as the field of telecommunication is advancing rapidly. The spectrum was underutilized because of fixed spectrum assignment policy and this valuable spectrum can be utilized efficiently by cognitive radio technology. READ MORE

  5. 4. Impact of Interference from Primary User on the Performance of Cognitive Radio Networks

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Maarig Aregawi Hagos; Marshed Mohamed; [2012]
    Keywords : cognitive radio; ergodic capacity; outage probability; SIMO; SINR;

    Abstract : This thesis report presents background knowledge about cognitive radio network (CRN) and investigates performance of underlay cognitive radio networks based on an adaptive power allocation policy of secondary transmitter (SU-Tx). In particular, it has been assumed that SU-Tx and primary user transmitter (PU-Tx) are equipped with a single antenna, while the corresponding receivers are equipped with multiple antennas.

  6. 5. Directional Spectrum Sensing and Transmission Using a Sector Antenna

    University essay from Institutionen för informationsteknologi och medier

    Author : Bilal Hasan Qureshi; [2012]
    Keywords : Spectrum Sensing; Ray-tracing and Sector Antennas;

    Abstract : Spectrum sensing plays a key role for radio resource awareness in cognitive radio. To enhance the capabilities of cognitive radio nodes, exploiting the spatial resource in addition to frequency and time re-sources seems reasonable. READ MORE
