ABSTRACT:
A method and apparatus for modulating a data signal for transmission over a channel of a communication system, wherein a direct modulation scheme is applied to a data signal over a given first signal interval. Subsequently, a control measure is determined for switching the modulation scheme for the data signal from the direct modulation scheme to a differential modulation scheme and/or vice versa, which is applied to the data signal over a given second signal interval.
