  1. 6. New Code Design and Analysis Tools for Serially Concatenated Systems

    Författare :ANDERS NILSSON; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In-line bit interleaving has over the last decade been used in a number of papers, and has proven to be very effective. Although it has several advantages over conventional bit interleaving, the use of conventional bit interleaving is still far more common. LÄS MER

  3. 7. In-Line Bit Interleaved Serially Concatenated Coded Modulation

    Författare :ANDERS NILSSON; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; serially concatenated codes; the AWGN channel.; Coded modulation; iterative decoding; in-line bit interleaving; turbo codes;

    Sammanfattning : A communication system using in-line bit interleaved serially concatenated trellis coded modulation (SCTCM) over the additive white Gaussian noise (AWGN) channel is investigated. In-line bit interleaving refers to an interleaving method for which the random bit interleaver is divided into several independent constituent bit interleavers. LÄS MER

  4. 8. Reduced Receivers for Faster-than-Nyquist Signaling and General Linear Channels

    Författare :Adnan Prlja; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital data transmission; receivers; decoders; channel modeling; intersymbol interference; ISI; MIMO; Faster-than-Nyquist signaling; complexity reduction; observation models; BCJR algorithm; turbo equalization; iterative detection; channel shortening;

    Sammanfattning : Fast and reliable data transmission together with high bandwidth efficiency are important design aspects in a modern digital communication system. Many different approaches exist but in this thesis bandwidth efficiency is obtained by increasing the data transmission rate with the faster-than-Nyquist (FTN) framework while keeping a fixed power spectral density (PSD).
