Prediction-based FM stereo radio noise reduction

An apparatus configured to reduce noise of a received multi-channel FM radio signal;

• wherein the received multi-channel FM radio signal is representable as a received mid signal and a received side signal;
• wherein the received side signal is indicative of a difference between a left signal and a right signal of the received multi-channel FM radio signal;
• the apparatus comprising
• a parameter determination unit configured to determine one or more parameters indicative of a correlation and/or decorrelation between the received mid signal and the received side signal;
• wherein the parameter determination unit is configured to determine a decorrelation parameter b indicative of a decorrelation between the received mid signal and the received side signal;
• and
• a noise reduction unit configured to generate a noise-reduced side signal from the received mid signal using the one or more parameters;
• wherein the noise reduction unit is configured to generate the noise-reduced side signal also from a decorrelated version of the received mid signal using the decorrelation parameter b;
• wherein the received side signal is not in a signal path for the generation of the noise-reduced side signal.
