  1. 1. Spectrum auctions in Sweden : A theoretical study of spectrum auctions in Sweden

    Kandidat-uppsats, Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Författare :Gustaf Smedman; Timo Kervinen; [2020]
    Nyckelord :Vickrey; CCA; SMRA; Radio spectrums; Single object Auction; Multiple object Auction; Price discovery; Truthful bidding; Collusive behaviour;

    Sammanfattning : This paper seeks to find whether the spectrum auctions in Sweden have been conducted efficiently and if there is a de facto model that suits all auctions. The efficiency is conditions that emphasise truthful bidding, price discovery and limits collusive behaviour. LÄS MER

  3. 2. Outage Probability Analysis of CooperativeCognitive Radio Networks Over κ − μ Shadowed Fading Channels

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

    Författare :Mahathi Poreddy; [2016]
    Nyckelord :Cognitive Radio Networks; Cooperative Communications; Decode-and-Forward Relays; Multiple-relay; Outage Probability;

    Sammanfattning : Over time, wireless technology advancements in the field of communications have been attracting every individual to turn into a wireless user. To accommodate the increasing number of users and to avoid the problem of spectrum scarcity, the concept of Cognitive Radio Network (CRN) has been developed. LÄS MER

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

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

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

    Sammanfattning : 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. LÄS MER
