Abstract
A new fast codeword search algorithm for vector quantisers is presente d. This algorithm performs a fast search in the wavelet domain of code words using the partial distance search technique. Simulation results show that the algorithm has only 2% of the arithmetic complexity of th e exhaustive search method.
