A radio transmitter and a method of operating a radio transmitter

摘要

By the present invention is provided an inventive radio transmitter and a method to operate a radio transmitter, by which the quality of a transmitted radio signal can be improved. The radio transmitter comprises at least one digital filter having adjustable parameters. Via a control signal input the transmitter can receive a feedback signal being indicative of the output signal from the transmitter. The radio transmitter comprises programmable digital circuitry adapted to analyzing the feedback signal and to generating an analysis result. The programmable digital circuitry is further adapted to adjusting the adjustable parameters of the digital filter in accordance with the analysis result.
