چکیده |
The presence of undetected direct path conditions in
the TOA (Time of Arrival)-based indoor geolocation
introduces major errors into distance measurements.
In the proposed location estimation, an improved
procedure is introduced in Ultra-wideband (UWB)
systems in Line of Sight (LOS) and Non-Line of Sight
(NLOS) multipath environments by incorporating the
skewness as new statistic information of multipath
channel. Weighted least square error (WLS) algorithm
is used to estimate source position in this paper.
Simulation results show effectiveness of the proposed
algorithm, by reducing source localization error.
Uncertainty region between NLOS and LOS
identification is reduced in the proposed method
compared to previous methods.. |
