| Abstract: | A design of a robust predictive vector quantizer for packet-loss channels is presented. A linear prediction-based quantizer is considered, in which the prediction residual is quantized by a multiple description vector quantizer, and a simple procedure is developed for iteratively improving the system components, including the linear predictor, for a given channel loss probability. Experimental results obtained by designing quantizers for a Markov source as well as for speech line spectral pairs are presented. | ||
