Patent ID: 7869486

Claim:
A tracking apparatus of a mobile communication system, comprising: a signal extractor for extracting an on-time energy signal, an early energy signal, and a late energy signal from a received signal; an interference remover for removing a multipath interference component contained in the early energy signal and the late energy signal; a location estimator for comparing an amplitude of the interference-removed early energy and an amplitude of the interference-removed late energy output from the interference remover to determine whether an accurate receiving position is extracted; a feedback circuit for inputting a difference value between the early energy and the late energy output from the location estimator to the signal extractor so that the difference value is used to extract the on-time energy signal, the early energy signal and the late energy signal; a descrambler for descrambling the on-time energy signal, the early energy signal, and the late energy signal; a dechannelizer for dechannelizing the descrambled on-time energy signal, the early energy signal, and the late energy signal; and a despreader for despreading the dechannelized on-time energy signal, the early energy signal, and the late energy signal.
