PILOT SIGNAL DETECTOR, DETECTION METHOD OF PILOT SIGNAL USED FOR THE SAME, AND REPORTING UNIT FOR BASE STATION USING THEM

摘要

PROBLEM TO BE SOLVED: To provide a pilot signal detector wherein the detection of a pilot signal is hardly affected by a noise component.;SOLUTION: A level discrimination unit 78 extracts the pilot signals from outputs of a detector 77, and when the level decision unit 78 can extract a plurality of the consecutive pilot signals with the same levels among the extracted pilot signals, the level decision unit 78 selects at least one representative value among them as positivity, and when the number of the extracted pilot signals reaches a predetermined value, a report signal generating means 80 generates a report signal. Only when the extracted consecutive pilot signals have the same voltages, since the representative value is regarded as positivity, the occurrence of erroneous determination caused by a noise component included in a transmission signal from a mobile unit can be decreased.;COPYRIGHT: (C)2006,JPO&NCIPI
