- Abstract
- This paper reports the empirical Ultra Wide Band
(UWB) channel model for short range outdoor environments. The
measurements were performed based on the frequency sweep
method in frequency domain at two different parking lot
environments. From the measured channel transfer functions,
parameters of log-distance path loss law and the effect of frequency
to the path loss exponent are extracted. The distribution of
received signal is analyzed to the existence of line-of-sight (LOS)
path also. For the characterization of frequency dependent UWB
channel parameters, standard deviation and correlation properties
of channel gain in frequency domain are analyzed. The standard
deviation increases with transmitter-receiver separation in LOS
condition and the correlation is regressed to the double-slope
model.
