Reception apparatus, path detection apparatus, method thereof, and computer product used in CDMA system base station

摘要

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.

1. A reception apparatus comprising:
a receiver that receives signals; and a processor configured to execute a programmed procedure including,
a path detection process performing path detection on a selected user equipment;a deriving process using a detected path timing to despread incoming signals from said selected user equipment and deriving one or more multipath components;a providing process Rake combining said one or more multipath components to provide a demodulation signal;a measuring process measuring an elapsed time from a previous path detection of each of a plurality of user equipment; anda scheduling process selecting one or more user equipment at predetermined intervals according to one or more predetermined judgment criteria then reporting to said path detection process;wherein said one or more predetermined judgment criteria comprise criteria for selecting the user equipment with a demodulation signal which has a higher fading frequency, and whereinsaid one or more predetermined judgment criteria further includes criteria for selecting the user equipment having a longer said elapsed time.
