Abstract
The embodiments relate to a method for encoding/decoding, the method comprising obtaining () a set of input samples; obtaining () a triangular matrix, a cross-correlation vector and a scaling vector by utilizing the set of input samples; determining () an intermediate vector with a first back-substitution using the triangular matrix and the cross-correlation vector; scaling () the intermediate vector using the scaling vector; determining () a filter coefficient vector with a second back-substitution using the triangular matrix and the scaled intermediate vector; and determining () predicted sample values for a block of samples based on the filter coefficient vector. The embodiments also relate to an apparatus and a computer program product for implementing the method.
