2. 21. Performance Trade-offs for Ultra-Reliable Low-Latency Communication Systems

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

   Abstract : 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. READ MORE

4. 22. Silica particle-induced NLRP3 inflammasome activation and DNA damage in respiratory epithelium

   Author : Rongrong Wu; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Respirable crystalline silica particles (CSi) can persist and induce inflammation and DNA damage in human lungs. Previous studies have used complex model systems to characterize CSi-induced DNA damage, involving co-cultures of epithelial cells and macrophages and long-term exposures, necessitating alternative models.

5. 23. Coordinated MultiPoint Transmission with Incomplete Information

   Author : Tilak Rajesh Lakshmana; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; scheduling; precoding; coordinated multipoint; joint transmission; backhauling; particle swarm optimization; decentralized; stochastic optimization; convex optimization; efficient backhauling; centralized;

   Abstract : The demand for higher data rates and efficient use of various resources has been an unquenchable thirst across different generations of cellular systems, and it continues to be so. Aggressive reuse of frequency resources in cellular systems gives rise to intercell interference which severely affects the data rate of users at the cell-edge. READ MORE

6. 24. Fading Channels: Capacity and Channel Coding Rate in the Finite-Blocklength Regime

   Author : Wei Yang; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Information-theoretic studies on the fundamental limits of communication over wireless fading channels typically rely on simplifying assumptions, such as perfect channel state information (CSI), infinite blocklength, and vanishing probability of error. Although these assumptions are reasonable for most of the current wireless communication systems, they may be inaccurate for next-generation wireless systems. READ MORE

7. 25. Data transmission in the presence of channel state information feedback

   Author : Behrooz Makki; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Novel communication techniques such as adaptive resource allocation are useful tools to increase the transmission efficiency and reliability of wireless networks. The main idea behind these techniques is to adapt some transmissionparameters, such as the transmission rate and power, based on the instantaneous channel quality. READ MORE
