Method and receiver for noise suppression in radio receiver of multichannel audio signals

摘要

the present invention relates to a method for the suppression of disturbances in the funkempfang multi-channel audiosendungen in two channel stereo audiosendungen, with a respective wanted signal per channel.here, during the reception of multi-channel audiosendung in periods in which the reception largely undisturbed, spectral distributions of nutzsignale of different channels and / or propagation time differences. zeitdifferenzen, each of two or more different spektralanteilen in the useful signal of different channels are compared.at the beginning of the empfangsstu00f6rung the last calculated vergleichsergebnissse used for each channel to at least two or more different spektralanteile parameters for a signaldu00e4mpfung and / or signal delays is established.for the duration of the empfangsstu00f6rung the corresponding spektralanteile from the nutzsignale channels in accordance with the specific parameters einkanalsignal containing delayed and / or subdued on the kanalzahl the multi-channel audiosendung corresponding channels in such a way that r for a listener for the corresponding spektralanteile a spatial klangeindruck is producedwhat is essentially a spatial klangeindruck reproduced audio signals of the channels corresponds to the right.
