摘要
Systems for performing general and computationally efficient methods of searching through N Vector Quantization (VQ) codevectors for a preferred one of the N VQ codevectors. The efficient method predicts a speech signal to derive a residual signal, derives a ZERO-INPUT response error vector common to each of the N VQ codevectors, derives N ZERO-STATE response error vectors each based on a corresponding one of the N VQ codevectors, and selects the preferred one of the N VQ codevectors based on the N ZERO-STATE response error vectors and the ZERO-INPUT response error vector.
