ABSTRACT:
The invention relates to a method for deriving noise statistical properties (NSP) for a signal (S) wherein first distorted noise statistical properties (DNSP) are derived from a distorted signal (DS). In addition the distorted noise statistical properties (DNSP) are subjected to a deconvolution/inversion process (S3) to thereby derive un-distorted noise statistical properties (NSP) for said underlying un-distorted signal (S).
