  1. 1. Optimizing Energy Efficiency in Wireless Links Through Reconfigurable Intelligent Surfaces and Optimal Ratios

    Författare :Anders Enqvist; Emil Björnson; Ozlem Tugfe Demir; Cicek Cavdar; Yuanwei Liu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 6G; Energy Efficiency; Reconfigurable Intelligent Surfaces; 6G; energieffektivitet; rekonfigurerbara intelligenta ytor; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : This thesis explores the optimization of energy efficiency (EE) in the radiolink of wireless communication systems, focusing on both the user equipment (UE) and the base station (BS). The first part of the study examines strategies to minimize the energy consumption of the UE when transmitting short data payloads, utilizing a reconfigurable intelligent surface (RIS) controlled by the BS, to improve the channel conditions.

    Nyckelord :HUMANIORA; HUMANITIES; maritime archaeology; digital archaeology; visualisation; contract archaeology; contract maritime archaeology; underwater dcoumentation; outreach; Archaeology; Arkeologi;

    Sammanfattning : This licentiate thesis investigates the use of digital visualisations for knowledge production and communication of maritime heritage located underwater. The archaeological practice that takes place in response to development, contract archaeology, is the field that is being investigated. LÄS MER

  4. 3. Inverse system identification with applications in predistortion

    Författare :Ylva Jung; Martin Enqvist; Lennart Ljung; Torkel Glad; Thomas Eriksson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; system identification; inverse models; signal processing; power amplifiers; predistortion; communication electronics;

    Sammanfattning : Models are commonly used to simulate events and processes, and can be constructed from measured data using system identification. The common way is to model the system from input to output, but in this thesis we want to obtain the inverse of the system. LÄS MER

  5. 4. Estimation of Inverse Models Applied to Power Amplifier Predistortion

    Författare :Ylva Jung; Martin Enqvist; Lennart Ljung; Torkel Glad; Mikael Sternad; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Mathematical models are commonly used in technical applications to describe the behavior of a system. These models can be estimated from data, which is known as system identification. Usually the models are used to calculate the output for a given input, but in this thesis, the estimation of inverse models is investigated. LÄS MER
