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

    Author : Andreas Buchberger; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Error correcting codes; learned decoders; machine learning; iterative decoding; probabilistic shaping; fiber-optic communications; pruning;

    Abstract : 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. READ MORE

  4. 2. Ultra-Reliable Short-Packet Communications: Fundamental Limits and Enabling Technologies

    Author : Johan Östman; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ultra-reliable low-latency; variablelength stop-feedback; imperfect CSI; channel estimation; HARQ.; joint detection and decoding; short packets; Block-fading channels; multiuser massive MIMO;

    Abstract : The paradigm shift from 4G to 5G communications, anticipated to enable ultra-reliable low-latency communications (URLLC), will enforce a radical change in the design of wireless communication systems. Unlike in 4G systems, where the main objective is to provide 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.
