  1. 16. 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).
