  • Abstract
    A new idea for waveform coding using vector quantisation (VQ) is introduced. This idea makes it possible to deal with codevectors much larger than before for a fixed bit per sample rate. Also a solution to the matching problem (inherent in the present context) in the L infinity -norm describing a measure of nearness is presented. The overall computational complexity of this solution is O(n 3 log 2 n). Sample results are presented to demonstrate the advantage of using this technique in the context of coding of speech waveforms.<>
