Abstract: Aiming at the unequal-scale bit error of the present data processing system problem caused by system noise and other factors, in order to solve the previous wavelet transform-based bit error correction algorithm, this paper proposes a kind of newefficient iterative bit error correction algorithm. The new algorithm will improve the bit error correction accuracy of multiple data streams in data processing systems, then improving the quality of image data. According to analysis of the results verified by Matlab, compared with the traditional error correction algorithm, the new error correction algorithm designed in this paper can significantly improve the bit error correction accuracy and quality of the image data.
