Method and device for conditioning a radio data signal for a broadcast receiver

A device for conditioning a radio data signal for a broadcast receiver, comprising:

• a conditioning unit having a processor, and
• a non-transitory computer-readable storage medium storing a computer program, which is executable by a processor, including:
• a program code arrangement having program code for conditioning a radio data signal for a broadcast receiver, by performing the following:
• reading in the radio data signal and a radio data clock signal;
• integrating a signal that is a function of at least one of the radio data signal and the radio data clock signal, to determine an integral value curve;
• decoding radio data signal information from the integral value curve, using at least one of the radio data clock signal and a phase position of the radio data signal;
• ascertaining radio data signal quality information which represents radio data signal quality, using at least one of the radio data signal and the phase position of the radio data signal, the radio data signal quality information representing the credibility of the decoded radio data signal information;
• and
• providing the radio data signal information and the radio data signal quality information to output a conditioned radio data signal from the broadcast receiver;
• wherein the phase position of the radio data signal is divided into a first phase having a phase angle of 0°, and a second phase having a phase angle of 180°, in the decoding, and wherein the first phase and the second phase are differentiated by applying a signum function to the radio data clock signal.
