  4. 12. Causal MMSE Filters for Personal Audio : A Polynomial Matrix Approach

    Author : Simon Widmark; Mikael Sternad; Anders Ahlén; Lars-Johan Brännmark; Fredrik Gustafsson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Personal Audio; Audio Pre-compensators; Causal Filters; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Abstract : This thesis is devoted to the study of synthesis of causal filters for generating personal sound zones. Personal sound zones, personal audio or personal sound is the theory and practice of steering sound in such a way that it is amplified in one region and suppressed in another. READ MORE

    Author : Mahmoud Zaher; Emil Björnson; Marina Petrova; Mikael Sternad; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 14. Anti-windup and Control of Systems with Multiple Input Saturations : Tools, Solutions and Case Studies

    Author : Jonas Öhr; Mikael Sternad; Anders Ahlén; Tore Hägglund; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Anti-windup compensator; saturating actuator; amplitude limiter; rate limiter; path anti-windup; double integrator; time-optimal control; container crane; spreader; hydraulic cylinder; Reglerteknik; Automatic control; Reglerteknik;

    Abstract : Control of linear systems with saturating actuators are considered and anti-windup compensators for multiple-input multiple-output systems, and robust, almost time-optimal controllers for double integrators with input amplitude saturations, are proposed.Windup effects are defined and anti-windup compensators aiming at minimizing the windup effects are proposed.
