  1. 6. 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

  2. 7. On The Performance Of Two-Way Amplify-And-Forward Relay Networks

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Le Nam Hoang; [2010]
    Keywords : two-way relay; amplify-and-forward; symbol error rate; average sum-rate; outage probability;

    Abstract : The new paradigm of cooperative communications is a promising resolution to carry out MIMO technique. In this thesis work, we study the performance of cooperative relay networks in which the transmission from a source to a destination is assisted by one or several relaying nodes employing amplify-and-forward (AF) and decode- and-forward (DF) protocols.

  3. 8. Wireless Imaging Using Cooperative Diversity of Relay Networks

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Ahsan Haroon; [2010]
    Keywords : DSTBC; SEP; AF; DF; ADF;

    Abstract : Transmit diversity generally requires more than one antenna at the transmitter.However, many wireless devices are limited by size or hardware complexity to one antenna. READ MORE

  4. 9. Performance of Cooperative Relay Protocols over an Audio Channel

    University essay from Kommunikationssystem

    Author : Thomas Wärme; [2009]
    Keywords : Relay; Cooperative transmission; audio channel;

    Abstract : In wireless transmissions the communication is often degraded by random fades, noise and other performance reducing phenomena. One way of improving the stability and reducing the error rates is to use relaying techniques where several nodes cooperate in a transmission between two of them. READ MORE
