  • Antenna subset selection for cyclic prefix assisted MIMO wireless communications over frequency selective channels 
    Wilzeck, A.; Kaiser, T. (Heidelberg : Springer Verlag, 2008)
    Antenna (subset) selection techniques are feasible to reduce the hardware complexity of multiple-input multiple-output (MIMO) systems, while keeping the benefits of higher-order MIMO systems. Many studies of antenna selection ...
  • Autonomous optimization of UWB link access 
    Pérez-Guirao, Maria D.; Luebben, Ralf; Kaiser, Thomas (Berlin : De Gruyter, 2009)
    We present a novel approach for interference management in low data rate IR-UWB networks that enables concurrent transmissions at full power while allows each source to independently adapt its pulse rate (transmitted pulses ...
  • Infrastructure-aided localization with UWB Antenna Arrays 
    Adamiuk, G.; Sczyslo, S.; Arafat, S.; Wiesbeck, W.; Zwick, T.; Kaiser, T.; Solbach, K. (Berlin : De Gruyter, 2009)
    This paper presents an approach for a precise 2D-localization of a mobile station in indoor scenarios using a single base station only. In the approach both, the Direction of Arrival (DoA) and the Time of Arrival (ToA), ...
  • Systematic design of output filters for audio class-D amplifiers via Simplified Real Frequency Technique 
    Hintzen, E.; Vennemann, T.; Mathis, Wolfgang (Göttingen : Copernicus GmbH, 2014)
    In this paper a new filter design concept is proposed and implemented which takes into account the complex loudspeaker impedance. By means of techniques of broadband matching, that has been successfully applied in radio ...
