1. A transmitter for generating a radio frequency (RF) transmit signal, comprising:
signal generation circuity 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 to frequency spread the RF transmit signal;
modulation circuitry configured to generate the RF transmit signal by modulating the RF carrier signal with a modulation control signal; and
modification circuity 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 to frequency de-spread the RF transmit signal.
