Abstract: A transmitter for generating a radio frequency, RF, transmit signal is provided. The transmitter includes signal generation circuitry configured to generate, based on a sequence of first control words each indicating a respective frequency shift with respect to a target frequency of the RF transmit signal, a RF carrier signal with sequentially varying frequency over time in order to frequency spread the RF transmit signal. Further, the transmitter includes modulation circuitry configured to generate the RF transmit signal by modulating the RF carrier signal with a modulation control signal. The transmitter additionally includes modification circuitry configured to generate the modulation control signal by modifying, based on the sequence of first control words, phase information of a baseband signal bearing information to be transmitted or phase information of a signal derived from the baseband signal in order to frequency de-spread the RF transmit signal.
