  1. 1. Analysis and Design of Spatially-Coupled Codes with Application to Fiber-Optical Communications

    Författare :Christian Häger; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bit mapper; generalized product codes; generalized low-density parity-check codes; bounded-distance decoding; density evolution; spatial coupling; staircase codes.; braided codes; Bit-interleaved coded modulation;

    Sammanfattning : The theme of this thesis is the analysis and design of error-correcting codes that are suitable for high-speed fiber-optical communication systems. In particular, we consider two code classes. The codes in the first class are protograph-based low-density parity-check (LDPC) codes which are decoded using iterative soft-decision decoding. LÄS MER

  2. 2. On Signal Constellations and Coding for Long-Haul Fiber-Optical Systems

    Författare :Christian Häger; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low-density parity-check codes; constellation optimization; fiber-optical communication; bit mapper; spatial coupling; detector; Bit-interleaved coded modulation;

    Sammanfattning : Motivated by the realization that even the enormous bandwidth available in an optical fiber is finite and valuable, the design of spectrally efficient long-haul fiber-optical communication systems has become an important research topic. Compared to other wireline technologies, e.g. LÄS MER

  3. 3. Religion, rock och pluralism : En religionssociologisk studie av kristen diskurs om rockmusik

    Författare :Andreas Häger; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Religion; discourse; institutional Christianity; legitimation; pluralism; popular culture; popular music; qualitative analysis; religion; religious symbols; rock music; symbolic universe; Religionsvetenskap Teologi; Religion Theology; Religionsvetenskap Teologi; religionssociologi; The Sociology of Religion;

    Sammanfattning : Rock music has during all of its almost 50 years of existence been the subject of criticism and debate. Much of this criticism has risen from religious circles. But also in these circles, rock music has its advocates. This thesis studies the reactions to rock music by spokespersons for institutional Christianity. LÄS MER
