ABSTRACT:
The strength of the signal or carrier in one or more transfer channels near the receiving channel of a radio device operating in a radio telephone system is measured, for example, with a MAHO measurement. The measurement result is used to calculate the disturbance caused by the transfer channel to the receiving channel, and, based on the acquired result, the frequency response of a filter included by the receiver is adjusted, for example, by changing the width or slope of the passband.
