    Author : Reza Moosavi; Erik G. Larssopn; Mikael Sternad; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : From its first appearance, wireless communications has changed thelife for many people worldwide. Currently, more than half of the world's population are using wireless devices for various purposes on a daily basis. READ MORE

  3. 3. Low-density parity-check codes : unequal error protection and reduction of clipping effects

    Author : Sara Sandberg; David Declercq; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Abstract : The invention of low-density parity-check (LDPC) codes made reliable communication possible at transmission rates very close to the theoretical limit predicted by Shannon. However, communication close to the Shannon limit requires very long codes and results in long delay and high encoder and decoder complexity. READ MORE

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

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

    Abstract : 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.

  5. 5. Improving the Efficiency of Control Signaling in Wireless Multiple Access Systems

    Author : Reza Moosavi; Erik G. Larsson; Danyo Danev; James Gross; Linköpings universitet; []
    Keywords : ;

    Abstract : Prior to the transmission of payload data in any multiple access system, there is generally a need to send control information such as scheduling assignments, transmission parameters and HARQ acknowledgments. This process is called control signaling and has a significant impact on the overall system performance. READ MORE
