Abstract: A signal processing device is usable in a communication system and includes a signal path, a signal detector, a signal synthesizer, a transmission unit, and a receive path including an analog-to-digital converter. The signal path transmits a transmission signal that was transmitted by the communication system and that contains a communication signal. The signal detector detects, and generates an activation signal in response to, an interference signal contained in the transmission signal and occurring due to narrowband interferences. The signal synthesizer generates an approximation signal for the interference signal upon the presence of the activation signal. The transmission unit receives the transmission signal transmitted by the signal path and the approximation signal, and outputs a difference signal between the transmission signal and the approximation signal. The analog-to-digital converter converts a signal generated based on the difference signal into a digital signal.
