    Sammanfattning : The digital signal processing (DSP) circuits used in the fiber-optic communication links that make up the backbone of the Internet can be a significant contributor the over-all power dissipation of a link. As the number of connected users and their bandwidth requirements are expected to continue to grow over the coming years, the development of power-efficient high-throughput DSP systems is a critical factor in enabling this growth.

  7. 5. Adaptive blind deconvolution using third-order moments : exploiting asymmetry

    Författare :Patrik Pääjärvi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Sammanfattning : This thesis focuses on the use of third-order statistics in adaptive blind deconvolution of asymmetric impulsive signals. Traditional methods are typically based on fourthorder moments, which can discriminate signals with heavy-tailed probability functions (i.e. `spiky' signals) from corresponding filtered versions.
