    Sammanfattning : The work presented in this thesis concerns interferencesuppression techniques in two different communication systems.In the first part we study fiber-optic systems with practical non-ideal transmitters and receivers, which give rise to intersymbol interference (ISI). LÄS MER

  7. 10. Channel Shortening in Wireless Communication

    Författare :Sha Hu; Kommunikationsteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Channel shortening CS ; multi-input multi-output MIMO ; intersymbol interference ISI ; achievable information rate AIR ; partial marginalization PM ; dirty paper coding DPC ; large intelligent surface LIS ; Cramér-Rao lower bound CRLB ;

    Sammanfattning : The concept of Channel Shortening (CS) is a well-known technique that has a rich history over 40 years. CS transfers linear vector channels such as multi-input multi-output (MIMO) and intersymbol interference (ISI) channels into ``shortened'' versions, for the purpose of reducing demodulation-complexity and improving data-transmission performance.
