摘      要：The authors present a new approach to combined source-channel coding based on using the reliability information available from the Turbo-code channel decoder. Numerical results are presented for the transmission of the DCT coefficients of still images showing a noticeable improvement with respect to an ordinary, as well as a channel optimised quantiser.
