  1. 1. Spatially Coupled Codes in Turbo Equalization

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

    Författare :Mgeni Makambi Mashauri; [2019]
    Nyckelord :Turbo equalization; spatial coupling; waterfall versus error floor; codes on graphs; iterative receivers; LDPC codes in turbo equalization; Technology and Engineering;

    Sammanfattning : In this thesis we investigate the application of spatial coupling in turbo equalization. We show that with spatial coupling we can have a fresh perspective on the trade-off between performance in the waterfall and error floor region often encountered in the choice of codes for turbo equalization.

  2. 2. Iterative Channel Estimation in LTE Uplink

    Master-uppsats, KTH/Kommunikationsteori

    Författare :Erik Lindén; [2014]
    Nyckelord :;

    Sammanfattning : An algorithm for iterative channel estimation using soft feedback for LTE uplink is proposed. The algorithm has low complexity compared to MMSE estimation and does not require knowledge of the channel statistics. LÄS MER

  3. 3. Turbo Equalization for HSPA

    Uppsats för yrkesexamina på avancerad nivå, Linköpings universitet/Kommunikationssystem

    Författare :Cagatay Konuskan; [2010]
    Nyckelord :Turbo equalization; MMSE; HSPA; ISI; decoding; equalization; low complexity; HARQ;

    Sammanfattning : New high quality mobile telecommunication services are offered everyday and the demand for higher data rates is continuously increasing. To maximize the uplink throughput in HSPA when transmission is propagated through a dispersive channel causing self-interference, equalizers are used. LÄS MER

  4. 4. Implementation Aspects of 3GPP TD-LTE

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Ningning Guo; [2009]

    Sammanfattning : 3GPP LTE (Long Term Evolution) is a project of the Third Generation Partnership Project to improve the UMTS (Universal Mobile Telecommunications System) mobile phone standard to cope with future technology evolutions. Two duplex schemes FDD and TDD are investigated in this thesis. LÄS MER
