Reception apparatus, path detection apparatus, method thereof, and computer product used in CDMA system base station
Abstract:
A reception apparatus used by a Code Division Multiple Access (CDMA) system base station includes a path detection unit performing path detection on a selected user equipment. Also included is a deriving unit using the detected path timing to despread incoming signals from said selected user equipment and deriving one or more multipath components. Also included is a providing unit Rake combining said one or more multipath components to provide a demodulation signal. Also included is a scheduling unit selecting one or more user equipments at predetermined intervals according to one or more judgment criteria and reporting to the path detection unit. The one or more judgment criteria includes criteria for selecting the user equipment with the demodulation signal which has a higher fading frequency.
