Abstract

We present a novel methodology for adaptive vector quantisation (AVQ), where the codebook is updated with new code-vectors. The new code-vectors replace less significant ones based on a scoring criterion that utilises a forgetting factor and a codebook half-life. The proposed method is shown to outperform conventional techniques of AVQ by approximately 1dB.
