Performance Analysis of UWB Systems in the Presence of
Timing Jitter
— Ismail G˜ uvenc› and H˜ useyin Arslan
Abstract: In this paper, performances of different ultra­wideband
(UWB) modulation schemes in the presence of timing jitter are
evaluated and compared. Static and Rayleigh fading channels are
considered. For fading channels, flat and dispersive channels are
assumed. First, bit error rate (BER) performances for each case
are derived for a fixed value of timing jitter. Later, a uniform dis­
tribution of jitter is assumed to evaluate the performance of the
system, and the theoretical results are verified by computer simu­
lations. Finger estimation error is treated as timing jitter and an
appropriate model is generated. Furthermore, a worst case distri­
bution that provides an upper bound on the system performance is
presented and compared with other distributions. Effects of tim­
ing jitter on systems employing different pulse shapes are analyzed
to show the dependency of UWB performance on pulse shape. Al­
though our analysis assumes uniform timing jitter, our framework
can be used to evaluate the BER performance for any given proba­
