    • A Bayesian approach to respiration rate estimation via pulse-based ultra-wideband signals 

      Soǧancı, Hamza; Gezici, Sinan; Arıkan, Orhan (IEEE, 2009)
      In this paper, theoretical limits on estimation of respiration rates via pulse-based ultra-wideband (UWB) signals are studied in the presence of prior information about respiration related signal parameters. First, a ...
    • Hybrid TW-TOA/TDOA positioning algorithms for cooperative wireless networks 

      Gholami, M.R.; Gezici, Sinan; Ström, E.G.; Rydström, M. (IEEE, 2011)
      The problem of positioning an unknown target is studied for a cooperative wireless sensor network using hybrid two-way time-of-arrival and time-difference-of-arrival measurements. A maximum likelihood estimator (MLE) can ...
    • Time delay estimation in cognitive radio systems 

      Kocak F.; Celebi H.; Gezici, S.; Qaraqe, K.A.; Arslan H.; Poor H.V. (2009)
      In cognitive radio systems, secondary users can utilize multiple dispersed bands that are not used by primary users. In this paper, time delay estimation of signals that occupy multiple dispersed bands is studied. First, ...
    • Time-delay estimation in dispersed spectrum cognitive radio systems 

      Kocak, F.; Celebi, H.; Gezici, S.; Qaraqe, K. A.; Arslan, H.; Poor, H. V. (SpringerOpen, 2010)
      Time-delay estimation is studied for cognitive radio systems, which facilitate opportunistic use of spectral resources. A two-step approach is proposed to obtain accurate time-delay estimates of signals that occupy multiple ...
