  2. 1. Ultra Wideband: Communication and Localization

    Author : Vijaya Parampalli Yajnanarayana; Peter Händel; Andreas Springer; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultra Wideband; TOA; Kalman Filter; Localization; Physical Layer Signaling; Location Aware Communication; Compressive Sampling; Sparse Signal Processing; Wireless Sensor Network; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The first part of this thesis develops methods for UWB communication. To meet the stringent regulatory body constraints, the physical layer signaling technique of the UWB transceiver should be optimally designed. READ MORE

  4. 2. Design and Fabrication of Ultra-Wideband Bandpass Filter Based on Liquid Crystal Polymer Substrates

    Author : Xia Zhang; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bandpass filter; Automotive radar systems; Liquid crystal polymer substrate; Ring-resonator theory; Ultra-wideband; Millimeter wave;

    Abstract : For millimeter (mm)-wave systems’ applications, as frequency is moving towards higher and higher bands, materials and integration technologies are witnessing higher performance demands and consequently higher constraints. From a material’s point of view, the selection of substrate material has recently drawn considerable attention in the design of the whole mm-wave system. READ MORE

  5. 3. Design, Fabrication and Characterization of Microwave Passive Devices on Liquid Crystal Polymer Substrates

    Author : Xia Zhang; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; co-planar waveguide; parallel-coupled line resonator; dual-mode ring resonator; millimeter wave; ultra-wideband; Bandpass filter; liquid crystal polymer substrate; printed monopole antenna;

    Abstract : For microwave/millimeter (mm)-wave systems’ applications, as frequency is moving towards higher and higher bands, materials and integration technologies are witnessing higher performance demands and constraints. The materials presently used as mm-wave substrates are either expensive or show unsatisfactory performance. READ MORE

  6. 4. On the Physical Layer of Ultra-Wideband Systems

    Author : Matts-Ola Wessman; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This licentiate thesis consists of two published conference papers, onetechnical report, and an introduction. The focus is on communication at bitrates of 100 Mbps and higher for single-user systems at short range up to 10meters. READ MORE

  7. 5. Ultra-Wideband Low-Noise Amplifier andSix-Port Transceiver for High Speed DataTransmission

    Author : Adriana Serban; Shaofang Gong; Ke Wu; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : Today’s data rates in wired networks can reach 100 Gbit/s using optical fiber while data rates in wireless networks are much lower - tens of Mbit/s for 3G mobile communication and 480 Mbit/s for ultra-wideband (UWB) short range wireless communications. This difference in data rates can mainly be explained by the limited allowed frequency spectrum, the nature of the radio signal and the high requirements imposed on all hardware designed for high speed and wideband wireless communications.
