Cell search method, communication synchronization apparatus/program, and portable terminal apparatus

摘要

A cell search method wherein a mobile station detects, for each slot in a predetermined unit, a correlation value between an input signal and a spreading code generated in the mobile station. The detection process for the correlation value is performed over several slots, the correlation values obtained in the slots being integrated to detect a correlation peak value. The integration process is ended when the number of paths, at which an integrated correlation value has reached a reference set value, reaches a path count set value. This shortens the integration time when reception conditions are good. <IMAGE>
