  1. 1. Projektering av lokalnät med fördjupning i selektivitet

    M1-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Lucas Ebers; Niklas Eriksson; [2019]
    Nyckelord :;

    Sammanfattning : In power system, when a local network with over head lines is replaced by a network laid underground, itchanges the characteristics of the material used and gives an opportunity for an updated sizing. The goal withthe project was to present a proposal of a reconstruction of a old local network to a modern local network andpresent a selective coordination plan for all the branches in the new network.

  3. 2. Implementation of 3GPP LTE QPP Interleaver for SiLago

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Spandan Dey; [2019]
    Nyckelord :Quadratic Permutation Polynomial; QPP; interleaver; SiLago; Address Generation Unit; AGU; 3GPP; LTE; turbo codes; parallel; Quadratic Permutation Polynomial; QPP; interleaver; SiLago; Address Generation Unit; AGU; 3GPP; LTE; turbo codes; parallel;

    Sammanfattning : Modern wireless communication systems have seen an increased usage of various channel coding techniques to facilitate improved throughput and latency. Interleavers form an integral part of these coding techniques and play a critical role by making the communication more robust and resilient to noise and other interference. LÄS MER

  4. 3. A comparison of Polar Code Constructions and Punctur-ing methods for AWGN and Fading channels

    Master-uppsats, KTH/Teknisk informationsvetenskap

    Författare :Jonas Sedin; [2017]
    Nyckelord :;

    Sammanfattning : Today 5G and other wireless standards are being developed for the future of our society. The different use-cases of future wireless services are going to be ever-more demanding, whether it is vehicular communication or low-powered sensor networks. LÄS MER

  5. 4. Time-Multiplexed Channel Switches for Dynamic Frequency Band Reallocation

    Master-uppsats, Linköpings universitet/Datorteknik

    Författare :Roland Stenholm; [2016]
    Nyckelord :parallel; interleaver; bitonic; sorter; clos; network; sts; switch; dfbr; dynamic; frequency; band; reallocation;

    Sammanfattning : A partially parallel reconfigurable channel switch is constructed for use in DFBR. Its permutation can be changed while running without any interruption in the streams of data. Three approaches are tried: one based on asorting network, one based on memories and multiplexers and one based on a Clos network. LÄS MER

  7. 5. Analysis of the Performance of Different DWDM FilterTechnologies for Mobile Fronthaul Applications

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Fredrik Ahlbom; [2016]
    Nyckelord :DWDM; mobile fronthaul; C-RAN; AWG; TFF; Interleaver; DWDM; mobile fronthaul; C-RAN; AWG; TFF; Interleaver;

    Sammanfattning : In recent years, several studies and simulations have been made on changing the current Radio Access Network (RAN) architecture into a more centralized access network where the base band processing is done in a central oce (CO) instead of out by the antenna site. This new architecture is denoted as the mobile fronthaul and is planned to be in use for the coming 5G network. LÄS MER
