  1. 31. Efficient high-speed on-chip global interconnects

    Författare :Peter Caputa; Christer Svensson; Hartmut Grabinski; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microelectronics; Global Interconnects; On-Chip Interconnects; Velocity-of-Light Delay; On-Chip Communication; Low-Latency; Transmission Lines; Electronics; Elektronik;

    Sammanfattning : The continuous miniaturization of integrated circuits has opened the path towards System-on-Chip realizations. Process shrinking into the nanometer regime improves transistor performancewhile the delay of global interconnects, connecting circuit blocks separated by a long distance, significantly increases.

  3. 32. Development and evaluation of SAR algorithms for image formation and speed estimation in wideband SAR

    Författare :Thomas Sjögren; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Remote sensing and surveillance are the main application areas for radar in general and synthetic aperture (SAR) radar in particular. Since the first radar system built by Hülsmeyer in 1904, radar has developed so that it is now able to create images from a large distance. LÄS MER

  4. 33. Digital Dispersion Equalization and Carrier Phase Estimation in 112-Gbit/s Coherent Optical Fiber Transmission System

    Författare :Tianhua Xu; Sergei Popov; Gunnar Jacobsen; Jie Li; Magnus Karlsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coherent transmission; chromatic dispersion; carrier phase estimation; digital signal processing; Optics; Optik; Photonics; Fotonik; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Sammanfattning : Coherent detection employing multilevel modulation format has become one of the most promising technologies for next generation high speed transmission system due to the high power and spectral efficiencies. With the powerful digital signal processing (DSP), coherent optical receivers allow the significant equalization of chromatic dispersion (CD), polarization mode dispersion (PMD), phase noise (PN) and nonlinear effects in the electrical domain.

    Författare :Ellen F. Grumert; Jan Lundgren; Andreas Tapani; Francesc Soriguera; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Motorway traffic management systems are useful for improving the traffic conditions on urban motorways. One of the most common motorway traffic management systems are variable speed limit systems. LÄS MER

  7. 35. Event Based Sampling with Application to Spectral Estimation

    Författare :Niclas Persson; Fredrik Gustafsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Event based sampling; Time based sampling; Tire pressure monitoring system;

    Sammanfattning : In this thesis event based sampling, estimation of a single resonance frequency and the application indirect tire pressure monitoring system are studied.Event based sampling is an alternative to traditional uniform or equidistant sampling. In event based sampled systems, signals are sampled only when certain pre-defined events take place. LÄS MER
