US Patent 7555077 Method for path-searcher scheduling

A method for adaptively scheduling activation of a path-searcher for a mobile terminal operative in a telecommunication system. The mobile terminal is capable of receiving multi-path signals originating from a scattered signal from a transmitter of at least one base station in the telecommunication system. The time lag between consecutive path-searcher activations is according to the method determined based on a value of the power delay profile discrepancy between two consecutive power delay profiles. The power delay profiles are derived from at least a subset of the powers of signals received at different delays during the path-searcher activation.
