  1. 1. 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.

  2. 2. 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.

    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Fiber-optic communication; Real-time communication; Computer engineering; Datorteknik;

    Sammanfattning : Future parallel computer systems for embedded real-time applications,where each node in itself can be a parallel computer, are predicted to havevery high bandwidth demands on the interconnection network. Otherimportant properties are time-deterministic latency and guarantees to meetdeadlines. LÄS MER

  4. 4. High performance fiber-optic interconnection networks for real-time computing systems

    Författare :Magnus Jonsson; Bertil Svensson; Timothy M. Pinkston; Högskolan i Halmstad; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Fiber-optic communication; real-time communication; Computer engineering; Datorteknik;

    Sammanfattning : Parallel and distributed computing systems become more and more powerful and hence place increasingly higher demands on the networks that interconnect their processors or processing nodes. Many of the applications running on such systems, especially embedded systems applications, have real-time requirements and, with increasing application demands, high-performance networks are the hearts of these systems.

  5. 5. All-optical nonlinearity mitigation in fiber-optic communications

    Författare :Henrik Eliasson; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fiber-optic communications; phase-sensitive amplifiers; optical phase conjugation; nonlinear optics;

    Sammanfattning : The two main factors limiting the data throughput in modern fiber-optic communication links are the noise added by amplifiers and the nonlinear response of the optical fiber due to the Kerr effect. Today there are communication systems operating remarkably close to the limits set by these two factors. LÄS MER
