  1. 1. Secrecy Capacity of Cooperative Transmission with Opportunistic Relaying Scheme

    Master-uppsats,

    Författare :Dhathri Pravallika Pasumarthi; [2022]
    Nyckelord :Cooperative Transmission; Opportunistic Relaying; Decode-and-Forward; Outage Probability; Secrecy Capacity; Fading.;

    Sammanfattning : The usage of wireless communication has increased over the past few years. Most wired communications are replaced by wireless communication for ease of use. Wireless communication transfers confidential information like personal information and credentials between two entities. LÄS MER

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

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

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

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

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

    Sammanfattning : 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).

  5. 4. Performance Analysis of 3-hop using DAF and DF over 2-hop Relaying Protocols

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Faisal Mehmood; Muneeb Ejaz; [2013]
    Nyckelord :Bit Error Rate; Cognitive Radio; Decode Amplify and Forward; Energy Detection; Probability of Detection; Rayleigh Fading; Relay Network;

    Sammanfattning : In wireless Communication, the need of radio spectrum increases nowadays. But in the system we are losing approximately 82-86% of spectrum most of the time due to the absence of Primary User (PU). To overcome this issue Cognitive Radio (CR) is an admirable approach. LÄS MER

  7. 5. Adaptive Modulation for Dual-Hop Amplify-and-Forward Relaying Networks with Partial Relay Selection under Co-Channel Interference

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Sohaib Ahmed Siddiqui; Mohammad Abbas Khan; [2013]
