  1. 1. Space-time processing and equalization for wireless communications

    Författare :Erik Lindskog; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Space-time processing; channel estimation; equalization; maximum likelihood sequence estimation; decision feedback equalization; interference suppression; robustness; Materialvetenskap; Materials science; Teknisk materialvetenskap; Signal Processing; signalbehandling;

    Sammanfattning : In this thesis several aspects of space-time processing and equalization for wire-less communications are treated. We discuss several different methods of improving estimates of space-time channels, such as temporal parametrization, spatial parametrization, reduced rank channel estimation, bootstrap channel estimation,and joint estimation of an FIR channel and an AR noise model.

  4. 3. MIMO Transceiver Design for Multi-Antenna Communications over Fading Channels

    Författare :Simon Järmyr; Björn Ottersten; Antonio Pascual-Iserte; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In wireless communications, the use of multiple antennas for both transmission and reception is associated with performance gains of fundamental nature. One such gain stems from the spatial-multiplexing capabilities of wireless multiple-input multiple-output (MIMO) channels: Many propagation environments admit several data streams to be conveyed in parallel over a single point-to-point link, setting the stage for significantly increased data rates.

  5. 4. High speed CMOS optical receiver

    Författare :Håkan Bengtson; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Optical communication develops very fast and is today the main method for long distance wired communication. However cost is still high. Looking back to the evolution of optical transmission systems, one main objective of system development has become more and more important; minimize cost per gigabytes per second per kilometre, Gb/s/km.
