<p>The present invention relates to a method and an arrangement for forming a calibration signal, in which arrangement a CDMA signal is used. The arrangement comprises means (200) for placing the calibration signal in the frequency band of the CDMA signal and amplification means (300) for amplifying the CDMA signal, in which CDMA signal information is sent. The arrangement comprises means (100) for attenuating the frequency band of the CDMA signal at least at one point and means (200) for forming and placing the calibration signal in the attenuated point of the frequency band.</p> |
