Error Correcting Source Decoding

Authors: K. Cinkler, K.-D. Kammeyer
Abstract: An a posteriori channel error correction method based on subband synthesis is presented in this paper. Using not downsampled subband signals, we estimate the positions and amplitudes of errors inserted during transmission, thus allowing a correction of the
subband signals and a resynthesis of a (nearly) error free signal. The method can be extended to multiple dimensions. Examples of transmitted (compressed) images are shown with and without this method. The results are very promising.
