Linear Prediction schemes make a prediction ^ x i of a data sample x i using p previous samples. It has been shown 1, 3] that as the order of prediction p ! 1, there is no gain to be obtained by coding subband samples. This paper deals with the less well understood theory of nite-order prediction and optimal coding from subbands which are generated by ideal… (More)
