Method and apparatus for determining the location of a remote station in a CDMA communication network United States Patent 06188354

06188354 is referenced by 204 patents and cites 4 patents.

An apparatus and method for locating a remote station in a synchronous communications network using the time of arrival of a reference pilot signal at the remote station as a time reference. The time difference of arrival (TDOA) of GPS signals received by the remote station and other signals received from a base station, are measured relative to this reference time. From these measurements, the location of the remote station is determined. The invention treats the location issue as a TDOA problem.
