    Sammanfattning : This paper, on the identities shown in one of the cameos in Empress Josephine’s pearl and cameo diadem, has first of all focused on the mythological characters, and thereafter raised the question if these are to be seen as an allegory for people from the time. The process of identi-fication has followed the three levels in Panofsky’s method for analysing art, where the first and second levels consist of already known material from the Bernadotte Library, Royal Palace in Stockholm and the jeweller house of Chaumet (former Nitot et Fils) in Paris.

  3. 2. Performance Analysis of a MIMO Cognitive Cooperative Radio Network with Multiple AF Relays

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

    Författare :Advaita Advaita; Mani Meghala Gali; [2016]
    Nyckelord :Cognitive radio; Cooperative communications; Space time coding; MIMO systems; Outage probability;

    Sammanfattning : With the rapid growth of wireless communications, the demand for the various multimedia services is increasing day by day leading to a deficit in the frequency spectrum resources. To overcome this problem, the concept of cognitive radio technology has been proposed which allows the unlicensed secondary user (SU) to access the licensed spectrum of the primary user (PU), thus improving the spectrum utilization.

  4. 3. Performance Analysis of Piecewise-and-Forward Relay Network on Rayleigh Fading Channel

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

    Författare :Farnaz Gharari; [2015]
    Nyckelord :Cooperative communications; Relay Networks; Rayleigh channels; Radio communication Protocols; Master of Science Programme in Electrical Engineering with emphasis on Signal Processing Masterprogram i Elektroteknik med inriktning mot signalbehandling;

    Sammanfattning : The rapid changes and developments in cellular and wireless networks aim to provide more reliable communications with high data rate transmission. So far, one solution which is being considered for improving the reliability and eciency of mobile communications is cooperative communications. LÄS MER

  5. 4. Measurement Based Vehicle-to-Vehicle Multi-link Channel Modeling and Relaying Performance

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Xi Chen; [2015]
    Nyckelord :V2V; wireless; channel model; multilink; relaying; sum of sinusoids; correlated Gaussian; maximum likelihood estimation; Technology and Engineering;

    Sammanfattning : There has been intense research in vehicular communication in order to provide reliable low-latency vehicular communication links for developing intelligent transportation system (ITS). As one of the important properties, vehicle-to-vehicle (V2V) communication is learned to be inherently non-stationary due to the high mobility of both transmitter (TX) and receiver (RX). LÄS MER

  7. 5. 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
