  1. 6. Secure device to device communication

    University essay from KTH/Kommunikationsteori

    Author : Nathalie Sahlström; [2014]
    Keywords : ;

    Abstract : Since wireless communication has become a standard feature in the daily life, smartphones and tablets among other things are integrated with the Bluetooth technology. While in some parts of the day wireless communication can be used for searching the internet and share information on social networks without the need of having a secure connection, there are some other parts where the security might become of high importance.

  2. 7. The Performance of Dual-Hop Decode-and-Forward Underlay Cognitive Relay Networks with Interference Power Constraints over Weibull Fading Channels

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Andawattage Chaminda Janaka Samarasekera; [2014]
    Keywords : Cognitive Radio; Weibull Fading Channels; Cooperative Communication; Cognitive Relay Networks;

    Abstract : With the rapid development and the increasing use of wireless devices, spectrum scarcity has become a problem. The higher frequencies have bad propagation characteristics and the lower frequencies have low data rates, therefore the radio spectrum that is available for efficient wireless transmission is a limited resource.

  3. 8. Optimized Training Signal Design

    University essay from KTH/Signalbehandling

    Author : Marie Maros; [2014]
    Keywords : ;

    Abstract : In this thesis, the problem of finding an optimal training sequence for estimating a MIMO flat fading channel with spatially and temporally correlated Gaussian noise is considered.The methods analyzed tailor the training sequence not only according to the known statistical CSI but also to the specific purpose the channel estimate will fulfill.

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

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap; Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Sohaib Ahmed Siddiqui; Mohammad Abbas Khan; [2013]
    Keywords : Amplify-and-forward; BER; Outage Probability; SNR; Spectral Efficiency;

    Abstract : A new era of wireless communications combats with many challenges, including the performance issues and the demand of higher data rate. Upcoming generations of wireless communications will bear the resemblance in terms of same issues. READ MORE

  5. 10. Capacity Analysis of Cognitive Radio Relay Networks under Transmission and Interference Power Constraints

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Abhijith Gopalakrishna; [2012]
    Keywords : effective capacity; outage capacity; ergodic capacity; cognitive radio; relay networks;

    Abstract : This thesis investigates the performance of cognitive radio relay networks (CRRN) in Rayleigh fading channel under various power constraints. Here spectrum sharing approach is considered, whereby a secondary user (SU) may be allowed to transmit simultaneously with a primary user (PU) as long as SU interference to PU remains below a tolerable level.
