  1. 1. Faster than Nyquist Signaling with Spatial Coupling

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Haoran Liu; Lingwei Zhang; [2022]
    Keywords : Technology and Engineering;

    Abstract : The emergence of the Faster-Than-Nyquist signaling (FTN) technology has im- proved the tight spectrum resources by compressing the transmission interval between adjacent pulses. In a natural environment, data transmission via a wire- less medium and through multi-path, at a high data rate, the leakage of these paths among symbols can cause severe inter-symbol interference (ISI).

  3. 2. Spatially Coupled Codes in Turbo Equalization

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

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

    Abstract : 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.

  4. 3. Iterative Channel Estimation in LTE Uplink

    University essay from KTH/Kommunikationsteori

    Author : Erik Lindén; [2014]
    Keywords : ;

    Abstract : 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. READ MORE

  5. 4. Turbo Equalization for HSPA

    University essay from Kommunikationssystem

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

    Abstract : 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. READ MORE

  6. 5. Implementation Aspects of 3GPP TD-LTE

    University essay from Institutionen för systemteknik

    Author : Ningning Guo; [2009]
    Keywords : 3GPP LTE; FDD; TDD; OFDM; SC-FDMA; MIMO; FFT; IFFT; SDR;

    Abstract : 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. READ MORE
