  1. 21. 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.

  3. 22. Performance Analysis of Cognitive Radio Network over SIMO System

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Iqbal Hasan Haider; MD. Fazla Rabby; [2012]
    Keywords : Cognitive Radio; Outage Probability; Symbol Error Probability; Single Input Multiple Output; Selection Combining; Spectrum Sharing System.;

    Abstract : As resources are limited, radio spectrum becomes congested due to the growth of wireless applications. However, measurements address the fact that most of the licensed spectrums experience low utilization even in intensively teeming areas. READ MORE

  4. 23. Performance analysis of dual hop cellular networks

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Muhammad Adeel Islam; Khan Ahmad Shah; [2011]
    Keywords : Diversity techniques; wireless networks; fading channels; relay channels; outage probability; symbol error rate; bit error rate; multiple input multiple output; user cooperation.;

    Abstract : Explosive growth in wireless technology caused by development in digital and RF circuit fabrications put some serious challenges on wireless system designers and link budget planning. Low transmit power, system coverage and capacity, high data rates, spatial diversity and quality of services (QOS) are the key factors in future wireless communication system that made it attractive.

    University essay from KTH/Reglerteknik

    Author : Silvia De Lucia; [2010]
    Keywords : ;

    Abstract : We are witnessing a continuous development of heterogeneous wireless networks, such as cellular systems (e.g., the LTE, or long term evolution of the third generation wireless system), sensor networks, and satellite networks. READ MORE

  6. 25. 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.
