REDUCTION OF SPURIOUS UNCORRELATION IN FM RADIO NOISE |
摘要 |
<p>The document relates to audio signal processing, in particular to a system and a corresponding method for improving an audio signal of an FM stereo radio receiver, in this context, one aspect relates to the estimation of noise in a received side signal and the compensation of such noise in parametric stereo parameters. A system for generating a parametric stereo parameter from a two-channel audio signal is described. The two-channel audio signal is presentable as a mid signal and side signal representative of a corresponding left and right audio signal. The system comprises a noise estimation stage configured to determine an impact factor characteristic for the noise of the side signal; and a parametric stereo parameter estimation stage configured to determine the parametric stereo parameter; wherein the determining is based on the two-channel audio signal and the impact factor.</p> |
