Speech Watermarking for Air Traffic Control Communication

The speech communication channel for flight control between Pilot and Tower is used to transmit additional data such as a flight number. The data should be available at the screen of the flight controller to gain additional confidence about the identiy of the communication partner. The problem is approached by using watermarking techniques, where data is embedded into a host signal without being perceptable for the receiver.
