   Författare :Ezzeldin Shereen; György Dán; Joe H. Chow; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phasor measurements unit; Time synchronization; Power system state estimation; Network Security; Time synchronization attacks; Precision time protocol; Machine learning; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Phasor Measurement Units (PMUs) constitute an emerging technology that is essential for various smart grid applications such as phase angle monitoring, power oscillation damping, fault localization, and linear state estimation. To obtain precise PMU measurements of voltage and current phasors, time synchronization in the order of 1 microsecond is typically required. LÄS MER

4. 28. Millimeter-wave Networking : Fundamental Limits, Scalable Algorithms, and Design Insights

   Författare :Hossein Shokri-Ghadikolaei; Carlo Fischione; Gabor Fodor; Muriel Madard; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : The current demands for extremely high data rate wireless services and the spectrum scarcity at the sub-6 GHz bands are forcefully motivating the use of the millimeter-wave (mmWave) frequencies. The main characteristics of mmWave communications are severe attenuation, sparse-scattering environment, huge bandwidth, vulnerability to obstacles and antenna misalignment, massive beamforming, and possible noise-limited operation.
