  4. 18. On Linear Transmission Systems

    Författare :Dzevdan Kapetanovic; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MIMO systems; Precoding; Information Theory; Single Carrier Systems; Linear Modulation; Faster-than-Nyquist Signaling.;

    Sammanfattning : This thesis is divided into two parts. Part I analyzes the information rate of single antenna, single carrier linear modulation systems. The information rate of a system is the maximum number of bits that can be transmitted during a channel usage, and is achieved by Gaussian symbols. LÄS MER

  5. 19. Evaluation and Compensation of Nonlinear Distortion in Multicarrier Communication Systems

    Författare :Ali Behravan; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinearity; Multicarrier communication systems; peak-to-average power ratio;

    Sammanfattning : In modern wireless communication systems with increasing data transfer rateand mobility, designing efficient transceivers is a key issue. Among differentchallenges, nonlinearity of high power amplifiers is a problem that has to beovercome by means of adding extra hardware or using more efficient signalprocessing algorithms. LÄS MER

  7. 20. Interference Mitigation and Synchronization for Satellite Communications

    Författare :Joel Grotz; Björn Ottersten; Dirk Slock; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; Signalbehandling;

    Sammanfattning :  Within this thesis, the satellite broadcast scenario of geostationary satellites is reviewed. The densely crowded geostationary arc in the common broadcast frequencies may create significant interference from adjacent satellites (ASI). LÄS MER
