Abstract :
The joint channel-source decoding scheme for using turbo codes to protect compressed image data proposed by Peng, Huang, Costello and Stevenson (see, Proc. 1998 IEEE International Symposium on Circuits and Systems, Monterey, California, 1998) is modified for subband coded images. Two different modifications are presented and compared. The factors affecting the performance of the schemes are studied. Both modified schemes show superiority over a separate decoding system.
