  1. 21. On Secure and Sequential Source Coding

    Författare :Hamid Ghourchian; Mikael Skoglund; Tobias J. Oechtering; Michèle Wigger; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Secure source coding is an important research area in recent years as it deals with the problem of transmitting sensitive information over insecure channels while protecting it from unauthorized access. This is particularly relevant in the context of modern communication systems where the data transmitted is often sensitive in nature and the threat of eavesdropping or data breaches is high. LÄS MER

  3. 22. Constellation Design under Channel Uncertainty

    Författare :Jochen Giese; Mikael Skoglund; Bertrand Hochwald; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Constellation design; diversity; fading channels; frequency-selective channels; joint channel estimation and data detection; multiple antennas; partial channel state information; wireless communication; Telecommunication; Telekommunikation;

    Sammanfattning : The topic of this thesis is signaling design for data transmission through wireless channels between a transmitter and a receiver that can both be equipped with one or more antennas. In particular, the focus is on channels where the propagation coefficients between each transmitter--receiver antenna pair are only partially known or completetly unknown to the receiver and unknown to the transmitter.
