    • Position estimation via ultra-wide-band signals 

      Gezici, Sinan; Poor, H. V. (IEEE, 2009-02-27)
      The high time resolution of ultra-wide-band (UWB) signals facilitates very precise position estimation in many scenarios, which makes a variety applications possible. This paper reviews the problem of position estimation ...
    • Theoretical limits for estimation of periodic movements in pulse-based UWB systems 

      Gezici, Sinan (Institute of Electrical and Electronics Engineers, 2007)
      In this paper, Cramer-Rao lower bounds (CRLBs) for estimation of signal parameters related to periodically moving objects in pulse-based ultra-wideband (UWB) systems are presented. The results also apply to estimation of ...
    • Theoretical limits for estimation of vital signal parameters using impulse radio UWB 

      Gezici, Sinan; Şahinoğlu, Z. (IEEE, 2007)
      In this paper, Cramer-Rao lower bounds (CRLBs) for estimation of vital signal parameters, such as respiration and heart-beat rates, using ultra-wideband (UWB) pulses are derived. In addition, a simple closed-form CRLB ...
    • Two-step time of arrival estimation for pulse-based ultra-wideband systems 

      Gezici, Sinan; Sahinoglu Z.; Molisch, A. F.; Kobayashi, H.; Poor, H. V. (SpringerOpen, 2008)
      In cooperative localization systems, wireless nodes need to exchange accurate position-related information such as time-of-arrival (TOA) and angle-of-arrival (AOA), in order to obtain accurate location information. One ...
