Method and system for estimating a subscriber's location in a cluttered area

A system for estimating a location of a subscriber unit in a wireless communication system service area comprising:

• means for calculating a set of characteristics associated with the reception of a model signal, wherein the model signal represents a signal transmitted from a selected location to a receiver location in a model that represents the wireless communication system service area;
• means for measuring a set of characteristics that describe a received signal at a receiver location in the wireless communication system service area, wherein the receiver location in the wireless communication system service area corresponds to the receiver location in the model;
• means for determining a relationship between the calculated set of characteristics and the measured set of characteristics;
• and
• means for estimating the location of the subscriber unit that transmitted the received signal responsive to the relationship between the calculated set of characteristics and the measured set of characteristics.
