Communication device and base station search method for use therein

摘要

An A/D conversion section (13) converts analog base band data from a radio section (12) into digital base band data. A despreading section (141) despreads the digital base band data to convert it into symbol data. An RSCP measuring section (142) converts the symbol data into power and measures an RSCP value. An RSCP threshold value judging section (143) compares the measured RSCP value with a preset RSCP threshold value and judges from a result of the comparison whether or not a base station is present. A frequency setting section (144) determines a next search frequency value according to a result of the judgment of the RSCP threshold value judging section. A synthesizer (122) of the radio section produces local data according to frequency data sent from the frequency setting section.
