    Sammanfattning : Data networks are an important part in an increasing number of applications with real-time and reliability requirements. To meet these demands a variety of approaches have been proposed. Forward error correction, which adds redundancy to the communicated data, is one of them. LÄS MER

  2. 2. Error Correction Coding for Optical CDMA

    Författare :Henrik Lundqvist; KTH; []
    Nyckelord :;

    Sammanfattning : The optical fiber is a very attractive communication mediumsince it offers a large bandwidth and low attenuation and cantherefore facilitate demanding services such as high-qualityvideo transmission. As the reach of optical fiber is beingextended to the access network it is economically attractive toshare fibers between different users without adding activecomponents in the network. LÄS MER

    Sammanfattning : The advent of the Internet not only changed the communication methods significantly, but also the life-style of the human beings. The number of Internet users has grown exponentially in the last decade, and the number of users exceeded 3.4 billion in 2016. LÄS MER

  4. 4. Energy-Efficient Digital Signal Processing for Fiber-Optic Communication Systems

    Författare :Christoffer Fougstedt; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Digital Signal Processing; Forward Error Correction; Fiber Optic Communication; Application Specific Integrated Circuits; Communication Systems; Non-linear Impairment Mitigation;

    Sammanfattning : Modern fiber-optic communication systems rely on complex digital signal processing (DSP) and forward error correction (FEC), which contribute to a significant amount of the over-all link power dissipation. Bandwidth demands are evergrowing and circuit technology scaling will due to fundamental reasons come to an end; energy-efficient design of DSP is thus necessary both from a sustainability perspective and a technical perspective.

  5. 5. High-Throughput Power-Efficient DSP for Fiber-Optic Communication Systems

    Författare :Christoffer Fougstedt; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Non-linear Impairment Mitigation; Application Specific Integrated Circuits; Forward Error Correction; Fiber Optic Communication; Digital Signal Processing; Communication Systems;

    Sammanfattning : Communication networks are a vital backbone of the modern society. Power dissipation of optical communication links and digital signal processing (DSP) subsystems for these links are a major concern as throughput requirements increase, and the number of deployed systems grows.
