Abstract
The present application relates to at least one digitally controlled oscillator and a data modulation device. More particularly, the digital polar transmitter comprises at least one digitally controlled oscillator configured to generate at least one frequency. The digital polar transmitter comprises a data modulation device, wherein the data modulation device comprises at least one data input terminal, at least one output terminal, and at least one frequency input terminal, wherein the output terminal is connected to the digitally controlled oscillator. The digital polar transmitter comprises a phase measuring device configured to measure phase information from the output signal of the data modulation device for every frequency sample. The digital polar transmitter comprises a phase error detecting device configured to detect a phase error at least depending on the measured phase information, wherein the phase error detecting device is configured to apply the detected phase error to the output signal of the data modulation device.
