    Sammanfattning : Modern communication systems are designed to enable reliable and fast information transfer. Therefore, efficient channel coding and decoding strategies are needed, which guarantee sufficiently low probability of erroneous reception with affordable receiver complexity. LÄS MER

  2. 2. Aspects of List-of-Two Decoding

    Författare :Jonas Eriksson; Thomas Ericson; Tom Høholdt; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; list decoding; Sudan s algorithm; Reed-Solomon code; Datatransmission; Datatransmission;

    Sammanfattning : We study the problem of list decoding with focus on the case when we have a list size limited to two. Under this restriction we derive general lower bounds on the maximum possible size of a list-of-2-decodable code. We study the set of correctable error patterns in an attempt to obtain a characterization. LÄS MER

  3. 3. On the Design of Error Control Coding for Wireless Communication Systems

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; joint source-channel decoding; Electrical engineering; Elektroteknik; a posteriori probability; soft decoding; list sequence decoding; incremental redundancy; retransmission; low-rate; parallel concatenated; convolutional codes; Turbo codes; Wireless; error correction;

    Sammanfattning : New wireless services such as mobile Internet, multimedia streaming and high speed packet data access are making their way to the market. Availability of low-cost equipment providing high transmission quality and efficient spectrum utilization is crucial to the success of these services. LÄS MER

  4. 4. On Probabilistic Shaping and Learned Decoders with Application to Fiber-Optic Communications

    Författare :Andreas Buchberger; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Error correcting codes; probabilistic shaping; pruning; fiber-optic communications; machine learning; learned decoders; iterative decoding;

    Sammanfattning : We live in an ubiquitously connected world whose backbone are optical fibers. Achieving high spectral efficiencies and hence high transmission rates requires a careful combination of forward error correction (FEC) and higher-order modulation. This is referred to as coded modulation. LÄS MER

  5. 5. Short-Packet Communications: Fundamental Performance and Key Enablers

    Författare :Johan Östman; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Rayleigh fading; Block-fading channels; Rician fading; variable-length stop-feedback; short-packet channel codes.; ultra-reliable low-latency;

    Sammanfattning : The paradigm shift from 4G to 5G communications, predicted to enable new use cases such as ultra-reliable low-latency communications (URLLC), will enforce a radical change in the design of communication systems. Unlike in 4G systems, where the main objective is to have a large transmission rate, in URLLC, as implied by its name, the objective is to enable transmissions with low latency and, simultaneously, very high reliability.
