Patent ID: 7420946

Claim:
A receiver provided in a mobile station communicating with at least two different types of base stations, the at least two different types of base stations using the same spread code sequences and different channel frequency, comprising: a radio frequency (RF) module for setting reception RF bands for the respective base stations in response to the generated frequency channel control data, and down-converting signals received in the set reception RF bands; a searcher for carrying out a pseudo-noise (PN) despreading operation for signals outputted from the RF signal, despreading the PN-despread signal to an orthogonal signal of a pilot channel and measuring intensities of the orthogonally despread pilot signal, and outputting a result of the measurement to the controller; a controller for sequentially setting a search time for the base stations at base station search times, outputting frequency channel control data for each corresponding base station at the set search time to the RF module, analyzing intensities of the pilot channel signals received from the base stations of the set frequency channels, and registering the base stations; and a display unit for indicating the base stations registered by the controller, wherein the display unit varies a color of a specified indicator arranged on a display area to a color of a predetermined base station and indicates at least one registered base station.
