A method of reducing multipath noise, apparatus for reducing multipath noise and FM receiver

2002 
An apparatus for reducing the multipath noise extracts a high-frequency signal from a demodulated signal which is obtained from a frequency-modulated signal, and generates a noise reduction coefficient from the extracted high frequency signal. The modulated signal is split into high and low frequency components, the high frequency component is multiplied by the noise reduction coefficient, and the resulting product is added to the low frequency components. An output signal is obtained thereby, in which, reduces the spike noise that characterizes a multipath reception of a frequency modulated signal having a relatively small deterioration of the other parts of the signal, including the parts between the noise spikes. The degradation or distortion can be further reduced by the demodulated signal is replaced by an interpolated signal while the noise peaks before the Niedefrequenzkomponente is disconnected.
