DIFFERENTIELLE KODIERUNG IM FREQUENZ BEREICH VON SINUSMODELL PARAMETERN

摘要

An encoding method is characterised by a step of encoding parameters of a given sinusoidal component in encoded frames either differentially relative to other components in the same frame or directly, i.e. without differential encoding. Whether the encoding is differential or direct is decided algorithmically. A first type of algorithm produces an optimal result using a method derived from graph theory. An alternative algorithm, which is less computing intensive, provides an approximate result by an iterative greedy search algorithm.
