Abstract:
The present invention provides a method and an apparatus for detecting at least one repeater between a base station and a mobile unit. The method includes determining a first estimate of a distance traveled by a signal on a wireless communication link between the base station and the mobile unit, determining a second estimate of the distance traveled by the signal on the wireless communication link between the base station and the mobile unit, and comparing the first and second estimates. The method also includes determining whether the signal was processed by the at least one repeater based upon comparing the first and second estimates.
