  1. 21. Data transmission in the presence of channel state information feedback

    Författare :Behrooz Makki; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Novel communication techniques such as adaptive resource allocation are useful tools to increase the transmission efficiency and reliability of wireless networks. The main idea behind these techniques is to adapt some transmissionparameters, such as the transmission rate and power, based on the instantaneous channel quality. LÄS MER

  4. 23. Novel Applications of Space-Time Processing for Wireless Systems

    Författare :Tommy Hult; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Space-time processing; Novel applications; Wireless communications;

    Sammanfattning : Space-time processing techniques have emerged as one of the most promising areas of research and development in wireless communications. Space-time processing signifies the signal processing performed on a system consisting of several antenna elements, whose signals are processed adaptively in order to exploit both the spatial (space) and temporal (time) dimensions of the radio channel.

  7. 25. Causal MMSE Filters for Personal Audio : A Polynomial Matrix Approach

    Författare :Simon Widmark; Mikael Sternad; Anders Ahlén; Lars-Johan Brännmark; Fredrik Gustafsson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Personal Audio; Audio Pre-compensators; Causal Filters; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Sammanfattning : This thesis is devoted to the study of synthesis of causal filters for generating personal sound zones. Personal sound zones, personal audio or personal sound is the theory and practice of steering sound in such a way that it is amplified in one region and suppressed in another. LÄS MER
