  6. 15. Performance Analysis of Selected Cooperative Relaying Techniques

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Muhammad Afaq; Sahibzada Muhammad Faheem; [2010]
    Keywords : Cooperative communication; Relaying techniques; Amplify-and-forward; Decode-and-forward; DtF; S-DtF; MRC;

    Abstract : Recently, cooperative communication has gained significant interest due to the fact that it exploits spatial diversity and provides capacity/performance gain over conventional single- input single-output (SISO) systems. A mobile node with single antenna can cooperate with a nearby mobile node having single antenna in multi-user environment to create the effect of virtual multiple antenna system. READ MORE
