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

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

    Abstract : 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. READ MORE

  2. 2. Reconfigurable Analog to Digital Converters for Low Power Wireless Applications

    Author : E. Martin I. Gustafsson; Ana Rusu; Georges Gielen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Integrated Circuits; Analog to Digital Converters; Wireless communication; Electronics Engineering; Electrical Engineering; Electronics; Elektronik;

    Abstract : The commercialization of Marconi’s radio transmission and reception, along with the development of integrated circuits in the 1960’s have facilitated many new consumer products for wireless communication, where the mobile phones or handsets are one. These handsets started out as a portable phone, mounted in cars, and have with time added additional services as Short Message Service, and have today become a media center with global positioning, and high-speed internet connection.

  3. 3. Enabling hardware technology for GNSS software radio research

    Author : Marcus Junered; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Abstract : Software Defined Radio (SDR), has become an increasingly popular alternative to traditional radio technology. In principle the incoming radio frequency signal is sampled as close to the antenna as possible to minimize noise, distortion and other hardware related effects which degrade the signal quality.

  4. 4. Spectrally Precoded OFDM-Design and Analysis

    Author : Medhat Mohamad; Jaap van de Beek; Rickard Nilsson; Mérouane Debbah; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; OFDM; spectral precoding; out of band emission; 5G; Signalbehandling; Signal Processing;

    Abstract : Despite shifting towards mm-wave bands, the sub-6 GHz band will continue to be a fundamental spectral band in 5G. However, the severe congestion in this band makes a well-constrained spectrum a critical requirementof 5G. READ MORE

  5. 5. Network Management for Dynamic and Heterogeneous Wireless Sensor Networks

    Author : Shunmuga Priyan Selvaraju; Mats Björkman; Ali Balador; Hossein Fotouhi; Maryam Vahabi; Cicek Cavdar; Mälardalens universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

    Abstract : Wireless Sensor Networks (WSNs) are interconnections of spatially distributed sensor nodes with low-power wireless communication. In comparison with traditional wireless networks, WSNs provide novel features in network architecture, which are known as low-cost networking, rapid formation, widespread arrangement, self-organisation, and ease of deployment.
