Turbo Iterative Principle For Signal Restoration

Signal restoration based on the Turbo iterative principle is proposed. For this purpose, two uncorrelated component signals issued from an original signal are considered; two complementary filters are designed to process the component signals respectively and the correlated information extracted from both filters are mutually exchanged in the iterative process. This scheme has achieved much better performance and reduced computational cost in restor ing signal with both additive and multiplicative noise model at a very low SNR.
