Abstract
A decoder in a communication system using channel optimized vector quantization and including an encoder stores active encoder centroids c corresponding to active indices i, an active index being defined as an index that has a predetermined source probability p >0 of being selected by the encoder for transmission to the decoder, source probabilities p 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.
