  2. 6. Wireless transmission in future cyber-physical systems

    Author : Hasan Basri Celebi; Mikael Skoglund; Petar Popovski; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Abstract : This thesis studies some fundamental aspects of wireless communication in future cyber-physical systems with special emphasis on constraints on computational complexity and channel state information (CSI) at the transmitter. First, major challenges in designing a suitable wireless communication solution for future cyber-physical systems are initially discussed. READ MORE

    Author : Milad Ganjalizadeh; Marina Petrova; Jens Zander; Petar Popovski; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 5G; availability; cyber-physical systems CPSs ; deep Q-networks DQN ; deep reinforcement learning; distributed learning; machine learning; network slicing; reliability; soft actor-critic SAC ; ultra-reliable low-latency communications URLLC ; wireless communications.; Informations- och kommunikationsteknik; Information and Communication Technology; Datalogi; Computer Science;

    Abstract : Cyber-Physical Systems (CPSs) are becoming ubiquitous in modern society, enabling new applications that rely on the seamless interaction between computing, communication, and physical processes. In this context, ultra-reliable low-latency communications (URLLC) emerges as a crucial element, reliably allowing the real-time exchange of critical data. READ MORE

  5. 8. Performance and Implementation Aspects of Nonlinear Filtering

    Author : Gustaf Hendeby; Fredrik Gustafsson; Petar Djurić; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; particle filtering; nonlinear filtering; fault detection; Cramer-Rao lower bound; Kullback divergence; intrinsic accuracy; Automatic control; Reglerteknik;

    Abstract : I många fall är det viktigt att kunna få ut så mycket och så bra information som möjligt ur tillgängliga mätningar. Att utvinna information om till exempel position och hastighet hos ett flygplan kallas för filtrering. I det här fallet är positionen och hastigheten exempel på tillstånd hos flygplanet, som i sin tur är ett system. READ MORE

  6. 9. Analysis and Design of Rateless Codes

    Author : Iqbal Hussain; Lars Kildehøj Rasmussen; Petar Popovski; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The invention of turbo codes and the re-discovery of sparse graph codes constitute a milestone in error-correction codes designed for communication and storage systems. Sparse graph codes such as low-density parity-check codes can offer a performance that approaches the previously elusive Shannon capacity with reasonable practical computational complexity.

  7. 10. Parallel Stochastic Estimation on Multicore Platforms

    Author : Olov Rosén; Alexander Medvedev; Petar Djuric; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Recursive estimation; Parallelization; Bayesian estimation; Anomaly detection; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Abstract : The main part of this thesis concerns parallelization of recursive Bayesian estimation methods, both linear and nonlinear such. Recursive estimation deals with the problem of extracting information about parameters or states of a dynamical system, given noisy measurements of the system output and plays a central role in signal processing, system identification, and automatic control.
