    Sammanfattning : The modular multilevel converter (MMC) has extensively been used in high-voltage, high-power applications such as high-voltage dc transmission systems and flexible alternating current transmission systems. The control of MMC submodules is conventionally realized using wired communication systems. LÄS MER

  3. 2. Improving the Efficiency of Control Signaling in Wireless Multiple Access Systems

    Författare :Reza Moosavi; Erik G. Larsson; Danyo Danev; James Gross; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Prior to the transmission of payload data in any multiple access system, there is generally a need to send control information such as scheduling assignments, transmission parameters and HARQ acknowledgments. This process is called control signaling and has a significant impact on the overall system performance. LÄS MER

  4. 3. An Emulation-Based Performance Evaluation Methodology for Edge Computing and Latency Sensitive Applications

    Sammanfattning : Cloud Computing, with its globally-accessible nature and virtually unlimited scalability, has revolutionized our daily lives since its widespread adoption in the early 2000s. It allows us to access our documents anywhere, keep in touch with friends, back up photos, and even remotely control our appliances. LÄS MER

  5. 4. Seamless Integration of Battery-Free Communications in Commodity Wireless Networks

    Författare :Carlos Pérez-Penichet; Thiemo Voigt; Frederik Hermans; James Gross; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Backscatter communications; battery-free communications; battery-less devices; RFID; backscatter;

    Sammanfattning : Ubiquitous sensing applications have countless potential benefits to society. However, batteries have long been an obstacle to their full development. Harvesting energy from the environment is a promising alternative to battery power, but traditional radio transceivers consume too much for most harvesters. LÄS MER

  7. 5. Performance Trade-offs for Ultra-Reliable Low-Latency Communication Systems

    Författare :Sebastian Schiessl; James Gross; Mikael Skoglund; Cenk Gursoy; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : In this dissertation, we consider wireless systems for ultra-reliable low-latency communication (URLLC). URLLC systems are required for example in industrial closed loop control systems, where data must be transmitted within a short target delay of at most a few milliseconds. LÄS MER
