| Abstract: | A new fast codeword search algorithm for vector quantisers is presented. This algorithm performs a fast search in the wavelet domain of codewords using the partial distance search technique. Simulation results show that the algorithm has only 2% of the arithmetic complexity of the exhaustive search method |
