  1. 6. Turbo Decoder with early stopping criteria

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

    Author : Henrik Ljunger; [2016]
    Keywords : LTE Turbo Decoder Low Power Stopping Criteria; Technology and Engineering;

    Abstract : The turbo code used in the 3GPP Long Term Evolution(LTE) standard have been chosen specifically to simplify parallel turbo decoding and thus achieving higher throughputs. The higher data rates however leads to an increased computational complexity and thus a higher power and energy consumption of the decoder. READ MORE

  3. 7. Turbo Code Performance Analysis Using Hardware Acceleration

    University essay from Linköpings universitet/Datorteknik

    Author : Oskar Nordmark; [2016]
    Keywords : Turbo code; hardware acceleration; digital signal processors; DSP; simulation; block error rate; BLER; pseudo random number generation; PRNG; 5G;

    Abstract : The upcoming 5G mobile communications system promises to enable use cases requiring ultra-reliable and low latency communications. Researchers therefore require more detailed information about aspects such as channel coding performance at very low block error rates. READ MORE

  4. 8. Analysis of the finite length performance of spatially coupled convolutional codes

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

    Author : Ardiana Osmani; Hector Moreno Trujillo; [2015]
    Keywords : Spatial coupling; convolutional codes; braided convolutional codes; parallel concatenated codes; spatially coupled parallel concatenated codes; spatially coupled braided convolutional codes; BCJR algorithm; Technology and Engineering;

    Abstract : Error control coding is an essential part of any well-designed digital communication system. It has been used in structures to protect the information, by enabling reliable delivery of digital data over unreliable communication channels. Even though this is an old topic, enlisted by Shannon in the late 40's, a lot of research is still going on. READ MORE

  5. 9. Low complexity algorithms for faster-than-Nyquistsign : Using coding to avoid an NP-hard problem

    University essay from KTH/Optimeringslära och systemteori

    Author : Emil Ringh; [2013]
    Keywords : ;

    Abstract : This thesis is an investigation of what happens when communication links are pushed towards their limits and the data-bearing-pulses are packed tighter in time than previously done. This is called faster-than-Nyquist (FTN) signaling and it will violate the Nyquist inter-symbol interference criterion, implying that the data-pulsesare no longer orthogonal and thus that the samples at the receiver will be dependent on more than one of the transmitted symbols.

  6. 10. Performance model of a very high bypass ratio counter rotating turbo fan engine

    University essay from KTH/Kraft- och värmeteknologi

    Author : Martin Perrin; [2012]
    Keywords : Performance engine counter rotating CRTF three-spool snecma gearbox;

    Abstract : Nowadays Snecma focuses on new engine architectures in order to meet the future demands in civil aviation. One of these considered concepts is aircrafts powered by counter rotating fan engines which aim at tackling both noise and polluting emissions. READ MORE
