<p>PROBLEM TO BE SOLVED: To provide a mobile station which adequately separates signals by performing an inverse spread processing normally for a CDMA mobile communication system. SOLUTION: In this invention, a mobile station is constituted by providing a band-stop filter 24 which can remove only a transmitted high-frequency signal between a frequency conversion part 16 which converts a received high-frequency signal into an intermediate-frequency signal and a variable gain amplifier 26 which is provided behind the frequency conversion part 16 and holds the gain of the converted intermediate-frequency signal proper.</p> |
