  1. 1. A Software-Defined Baseband for Satellite Ground Operations : Feasibility and Design

    Författare :Moses Browne Mwakyanjala; Jaap van de Beek; Élcio Jeronimo de Oliviera; Jaan Praks; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Software-Defined Radios; Satellite Ground Operations; Satellite Telemetry; Command; and Tracking; Onboard space systems; Rymdtekniska system;

    Sammanfattning : Satellite telemetry, tracking, and command (TT&C) is a crucial activity needed to maintainthe health of a spacecraft or sometimes to facilitate payload data download. TT&Cground operations are facilitated by a communication device known in the TT&C communityas a baseband. LÄS MER

  3. 2. System Design for Opportunistic Networks

    Författare :Sylvia T. Kouyoumdjieva; Gunnar Karlsson; Andrea Passarella; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; opportunistic communication; system design; mobility; energy-saving mechanisms; device-to-device communication; mobile data offloading; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Device-to-device communication has been suggested as a complement to traditional cellular networks as a means of offloading cellular traffic. In this thesis we explore a solution for device-to-device communication based on opportunistic content distribution in a content-centric network. LÄS MER

  4. 3. Iterative Learning Control : Analysis, Design, and Experiments

    Författare :Mikael Norrlöf; Svante Gunnarsson; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial robots; Robot programming; Robot modeling;

    Sammanfattning : In many industrial robot applications it is a fact that the robot is programmed to do the same task repeatedly. By observing the control error in the different iterations of the same task it becomes clear that it is actually highly repetitive. LÄS MER

  5. 4. Sensor Networks and Their Radio Environment : On Testbeds, Interference, and Broken Packets

    Författare :Frederik Hermans; Per Gunningberg; Edith Ngai; Andreas Terzis; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sensor networks; Testbed; Mobility; Interference classification; Packet corruption; Computer Science with specialization in Computer Communication; Datavetenskap med inriktning mot datorkommunikation;

    Sammanfattning : Sensor networks consist of small sensing devices that collaboratively fulfill a sensing task, such as monitoring the soil in an agricultural field or measuring vital signs in a marathon runner. To avoid cumbersome and expensive cabling, nodes in a sensor network are powered by batteries and communicate wirelessly. LÄS MER

  7. 5. Massive MIMO: Prototyping, Proof-of-Concept and Implementation

    Författare :Steffen Malkowsky; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Massive MIMO; Testbed Design; Prototyping; ASIP; Processor;

    Sammanfattning : Wireless communication is evolving rapidly with ever more connected devicesand significantly increasing data rates. Since the invention of the smartphoneand the mass introduction of mobile apps, users demand more andmore traffic to stream music, watch high-definition video or to simply browsethe internet. LÄS MER
