  • Abstract
    Minimum mean-squared distortion can be achieved by a maximum a posteriori probability (MAP) estimator utilising the reliability information available from the turbo-code channel decoder. Using the optimum MAP estimator in vector quantisation, numerical results show that MAP detection provides a significant improvement over the conventional mapping-based hard-decision source decoder
