摘要：A method of searching a signed codebook to quantize a vector includesweighting a shape codevector in a set of shape codevectors with a weighting function fora Weighted Mean Square Error (WMSE) criteria, to produce a weighted shape codevector.The method further includes correlating the weighted shape codevector with the vectorto produce a weighted correlation term. The method also includes determining, based ona sign of the weighted correlation term, a preferred one of a positive and a negativesigned codevector associated with the shape codevector. The method further includesdetermining whether one of the signed codevectors does not belong to an illegal spacedefining illegal vectors.
