Abstract
A form of modulation that is variable in terms of its number of steps is provided in a mobile communication system using a digital modulation of a modulation carrier. The number of steps of the modulation in the respective digital transmission channel is thereby adaptively matched to the respectively existing transmission conditions during operation such that a largely constant error probability is achieved in this transmission channel. The modulation method is to be preferably applied in a mobile communication system with combined time-division multiplex/frequency-division multiplex multiple access methods (TDMA/FDMA).
