ABSTRACT:
A method of compensating the dependence of the useful transmitter signal on the transfer function of a combiner filter in a mobile radio communication system includes filtering the useful transmitter signal in the base band before it is fed to the combiner filter. This is done in connection with carrier frequency modulation with a filter, the total transfer function of which at least approximately comprises the inverted value of the transfer function of the combiner filter transformed to the base band.
