Abstract
The location of a mobile unit in the service area of a CDMA cellular telephone system is predicted from a spatial probability distribution that is generated over a region of sub-cells within the service area. The spatial distribution, and hence the predicted location, is updated sequentially based on RF measurements provided by the mobile unit through the use of a Bayesian-update method.
