  • Method and apparatus for detecting fake path in receiver in mobile communication system
    Publication number: 20070189366
    Abstract: Disclosed is an apparatus and method for receiving a signal transmitted through a multi-path in a wireless communication system, and more particularly an apparatus and method for removing a fake path detected by the ripple of a baseband pulse shaping filter to detect the position of an effective multi-path signal in a direct sequence Code Division Multiple Access system. The method for detecting a fake path in a user equipment in a mobile communication system includes detecting peak indexes and peak energies of peaks of signals received from node B, performing a fake path check with respect to the peaks based on the peak indexes and peak energies, and allocating fingers to peaks which have been determined not to be caused by a fake path as a result of the fake path check.
