| Summary |
A statistical technique to calculate the location of a signal source,
e.g. a mobile phone, in a multipath, non--line of sight environment, is
proposed. The technique relies on angular spread and relative time of
arrival measurements of multipath signals received at a base station antenna
array. The source location is estimated using an a priori known
statistical model for the distribution of single bounce multipath
scatterers around the signal source, and fitting the measured channel impulse
response received at the base station to this model.
Further improvement in location estimation accuracy is demonstrated
using the Kalman filter, or time average filter on the time sequence of
location estimates in a moving scenario.
