1. 1. The Information-Theoretic Cost of Learning Fading Channels

   Författare :Wei Yang; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiple antennas; finite blocklength; outage capacity; block-fading channel; Shannon capacity; quasi-static fading;

   Sammanfattning : Recent results in communication theory suggest that significant throughput gains in wireless fading networks can be achieved by exploiting network coordination (e.g., CoMP, network MIMO, and interference alignment), provided that each node in the network has perfect channel knowledge.

   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cell-free massive MIMO; power allocation; sum-SE maximization; proportional fairness; spectral efficiency; deep learning; handover; cluster formation; pilot assignment; unknown interference; outage; multiuser MIMO.; Cellfri massiv MIMO; effektreglering; summa-SE-maximering; proportionell rättvisa; spektraleffektivitet; djupinlärning; överlämning; klusterbildning; pilottilldelning; okända störningar; avbrottsnivå; MIMO för flera användare.; Datalogi; Computer Science;

   Sammanfattning : The ever-growing demand of wireless traffic poses a challenge for current cellular networks. Each new generation must find new ways to boost the network capacity and spectral efficiency (SE) per device. A pillar of 5G is massive multiple-input-multiple-output (MIMO) technology. LÄS MER

4. 3. Security of Electricity Supply in Power Systems : Establishing a Global Framework for Assessing Power System Health and Analyzing Outage Statistics in Sweden

   Författare :Sanja Duvnjak Zarkovic; Patrik Hilber; Ebrahim Shayesteh; Christina Papadimitriou; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; security of electricity supply; power system health; outage statistics; data analysis; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : The primary objective of this thesis is to enhance the security of electricity supply by providing a holistic perspective and introducing a comprehensive framework for assessing power system health. This novel approach aims for a thorough evaluation of the system’s overall performance and well-being, using the physical dimensions of the security of supply as the foundation for a power system health index.

5. 4. Optimisation and Incentive Mechanisms for Robust Generation Dispatch and Capacity Investment in Electricity Markets

   Författare :Lamia Varawala; György Dán; Mohammad Reza Hesamzadeh; José Manuel Arroyo; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimal power flow; Look-ahead; $N-k$ contingency criterion; Renewable energy; Environmental externalities; Electricity generation capacity; Strategic behaviour; Incentives;

   Sammanfattning : Power systems constitute a large-scale critical infrastructure and therefore, it is crucial that their operation be robust to deviations from normal functioning of its independent components. Furthermore, due to their large size, any inefficiencies in electricity market design can be very costly and therefore, must be optimised. LÄS MER

7. 5. On the Performance of Underlay Cognitive Radio Networks with Interference Constraints and Relaying

   Författare :Charles Kabiri; Blekinge Tekniska Högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cognitive Radio Networks; Cognitive Cooperative Relay Networks; Underlay Spectrum Access; Interference Constraint; Outage Constraint;

   Sammanfattning : Efficiently allocating the scarce and expensive radio resources is a key challenge for advanced radio communication systems. To this end, cognitive radio (CR) has emerged as a promising solution which can offer considerable improvements in spectrum utilization. LÄS MER
