Multiple path delay time searcher in reverse link communication channel of a communication system employing a code division multiple access method

摘要

A multiple path delay time searcher at a signal demodulation mode of a reverse link communication channel of a mobile communication system employing a code division multiple access method. The multiple path delay time searcher includes a sample buffer for storing a signal received from an antenna of a base station as a sample; a delay time searcher for obtaining a correlation value between a signal at a specific search location designated by the sample buffer and a reference signal corresponding to a specific symbol; a signal processor for deciding whether there is a signal component in the specific search location using an accumulative average of the correlation values received from the delay time searcher; and a multiple path combiner for deciding the symbol designated in the delay time searcher.
