Abstract
A method and system for determining with enhanced accuracy a line of bearing and related signal characteristics of a mobile wireless transceiver in a cellular-telephone communications system is presented. Three or more conventionally configured antenna elements are used to provide a high resolution line of bearing estimate through disambiguation of positional parameters associated with inter-element signal characteristics derived from signal products. The high resolution line of bearing estimate can then be used to determine the location of the transmitter.
