  1. 1. Blind Channel Equalization for Shortwave Digital Radio Communications

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Tomas Busk; [2020]
    Nyckelord :Blind Channel Equalization; Equalization; adaptive filter; radio communication; Blind kanalutjämning; kanalutjämning; adaptivt filter; radiokommunikation;

    Sammanfattning : In this thesis the concept of Blind Channel Equalization has been examined and algorithms suitable to blindly equalize the channel are presented and evaluated on simulated data. The concept of blind equalization is to equalize a communica- tions channel without relying on a training sequence or pilot tone, which may be either unknown to the receiver or not exist at all.

  2. 2. Independent Project Thesis in Electrical Engineering : Design and implementation of digital filters

    Kandidat-uppsats,

    Författare :Linus Ryttermalm; Gustav Vallinder; [2019]
    Nyckelord :digital filters;

    Sammanfattning : This thesis describes and discusses design and implementation of digital filters inembedded systems. Digital filters provide great flexibility where an interchangeablefilter is needed and real valued components are limited. Common sampling problemssuch as aliasing and reconstruction are discussed and solved using analog filters. LÄS MER

  3. 3. Performance Evaluation of MathWorks HDL Coder as a Vendor Independent DFE Generation

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

    Författare :Elisabeth Pongratz; Roshan Cherian John; [2019]
    Nyckelord :MATLAB; Simulink; HDL Coder; XSG; DSPB; Technology and Engineering;

    Sammanfattning : This thesis aims to evaluate MathWorks HDL (Hardware Descriptive Language) Coder and compare the results with designs produced by its vendor dependent counterparts. The focus is mainly on evaluate the design effort needed to close timing and to get optimal resource mapping for a selected design. LÄS MER

  4. 4. All-Digital Aggregator for Multi-Standard Video Distribution

    Master-uppsats, Linköpings universitet/Kommunikationssystem

    Författare :Andreas Norén; [2018]
    Nyckelord :Flexible Aggregator; Multi-Standard; Oversampled Complex Modulated Filter Banks; Inner Channelizers; Computational Complexity; Symmetric Linear-Phase FIR Filters;

    Sammanfattning : In video transmission there is a need to compose a wide-band signal from a numberof narrow-band sub-signals. A flexible solution offers the possibility to place any narrow-band sub-signal anywhere in the wide-band signal, making better use of the frequency space of the wide-band signal. LÄS MER

  5. 5. Implementation of High-Speed 512-Tap FIR Filters for Chromatic Dispersion Compensation

    Master-uppsats, Linköpings universitet/Datorteknik; Linköpings universitet/Datorteknik

    Författare :Cheolyong Bae; Madhur Gokhale; [2018]
    Nyckelord :DSP; VHDL; FIR; Digital communication; Optical networks; Chromatic dispersion;

    Sammanfattning : A digital filter is a system or a device that modifies a signal. This is an essential feature in digital communication. Using optical fibers in the communication has various advantages like higher bandwidth and distance capability over copper wires. LÄS MER
