Abstract
This paper presents an a posteriori channel error correction method, based on subband synthesis. We estimate the position and amplitude of transmission errors using undownsampled subband signals, thus allowing correction of the subband signals and resynthesis of a nearly error-free signal. The method can be extended to multiple dimensions. Examples of images transmitted (compressed) with and without this method are shown. The results are very promising.
