  2. 6. Timing-Based Localization using Multipath Information

    Author : Andreas Bergström; Fredrik Gustafsson; Gustaf Hendeby; Fredrik Gunnarsson; Erik Leitinger; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The measurements of radio signals are commonly used for localization purposes where the goal is to determine the spatial position of one or multiple objects. In realistic scenarios, any transmitted radio signal will be affected by the environment through reflections, diffraction at edges and corners etc. READ MORE

    Abstract : Spin-torque and spin Hall nano-oscillators are nanoscale devices (about 100 nm) capable of producing tunable broadband high-frequency microwave signals ranging from 0.1 GHz to over 65 GHz that several research groups trying to reach up to 200 - 300 GHz. READ MORE

  5. 8. Antenna Designs Aiming at the Next Generation of Wireless Communication

    Author : Sadegh Mansouri Moghaddam; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phased array antenna; MIMO efficiency; CDF; Millimeter-wave; PoD; OTA; Ultra-Wideband UWB antenna; Tightly-Coupled Dipole Array TCDA .; RIMP; Random-LoS; 5G;

    Abstract : Millimeter-wave (mm-wave) frequencies have drawn large attention, specically for the fifth generation (5G) of wireless communication, due to their capability to provide high data-rates. However, design and characterization of the antenna system in wireless communication will face new challenges when we move up to higher frequency bands. READ MORE

  6. 9. Planning and Provisioning Strategies for Optical Core Networks

    Author : Ajmal Muhammad; Robert Forchheimer; Lena Wosinska; Massimo Tornatore; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Optical communication networks are considered the main catalyst for the transformation of communication technology, and serve as the backbone of today's Internet. The inclusion of exciting technologies, such as, optical amplifiers, wavelength division multiplexing (WDM), and reconfigurable optical add/drop multiplexers (ROADM) in optical networks have made the cost of information transmission around the world negligible.

  7. 10. Energy Constrained Wireless Sensor Networks : Communication Principles and Sensing Aspects

    Author : Erik Björnemo; Anders Ahlén; Mikael Sternad; Erik Larsson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wireless sensor network; communication under processing cost; wireless channels; fading; probability theory as logic; uncertainty; measurement capacity; Signal processing; Signalbehandling;

    Abstract : Wireless sensor networks are attractive largely because they need no wired infrastructure. But precisely this feature makes them energy constrained, and the consequences of this hard energy constraint are the overall topic of this thesis. READ MORE
