摘要

A decoder in a communication system using channel optimized vector quantization and including an encoder stores active encoder centroids ci corresponding to active indices i, an active index being defined as an index that has a predetermined source probability pi>0 of being selected by the encoder for transmission to the decoder, source probabilities pi and the bit error rate epsilon to dynamically estimate a decoded vector using a sub-optimal algorithm in which only the most significant contributions are considered.
