Zusammenfassung:	The present invention relates to a modulator for generating a modulated signal with a reduced transmit spectrum, comprising a tone-phase shift keying unit configured to generate a TPSK-modulated signal, and a phase shifter configured to apply a predetermined phase shift to the TPSK-modulated signal to obtain a phase-shifted TPSK-modulated signal with reduced phase jumps.
