  5. 4. Towards Fully Optimized BICM Transmissions

    Författare :Alex Alvarado; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; binary reflected Gray code; iterative decoding; pulse amplitude modulation; convolutional codes; trellis-coded modulation; coded modulation; Bit-interleaved coded modulation; quadrature amplitude modulation; hierarchical constellations; interleaver design;

    Sammanfattning : Bit-interleaved coded modulation (BICM) was introduced in 1992 as a new coded modulation (CM) scheme particularly well suited for fading channels and is nowadays considered the de facto CM scheme in wireless standards (HSPA, IEEE 802.11a/g/n, DVB-T2/S2/C2, etc.). LÄS MER

  7. 5. A Conceptual Model for Analysis of Automation Usability Problems in Control Room Settings

    Författare :Jonas Andersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Human-machine systems; control rooms; cognitive systems engineering; nuclear power; levels of automation; usability problems;

    Sammanfattning : The focus of this licentiate thesis lies on the problems that can emerge when humans and advanced control systems work together in control room environments. In the nuclear domain, automation is used extensively and it is important to maintain safe and efficient operations. LÄS MER
