  2. 1. Human Detection and Tracking with UWB radar

    Author : Melika Hozhabri; Maria Lindén; Nikola Petrovic; Martin Ekström; Robin Augustine; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; UWB radar; signal processing; human detection; elektronik; Electronics;

    Abstract : As robots and automated machineries are increasingly replacing the manual operations, protecting humans who are working in collaboration with these machines is becoming an increasingly important task. Technologies such as cameras, infra-red and seismic sensors as well as radar systems are used for presence detection and localization of human beings. 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. TDMA for Low Sampling Rate IR-UWB Receivers

    Author : Muhammad Adeel Ansari; Svante Signell; Ramir Eghbali; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In UWB communication sampling plays a key role in detection of the transmitted data. There are various methods of data transmission and detection at the receiver. Mostly, the detection methods are based on frequency domain methods. READ MORE

  6. 4. 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

  7. 5. 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
