| Abstract: | The paper first propose coding structure of turbo code and the maximum a posteriori algorithms which is used to itera- tive decoding .secondly, The paper introduce some kinds of in- formation hiding technology which based on different condition, also,compare the difference between the turbo code which have hidding information and the turbo code which have not hidding information in theory. Last,we simulate kinds of technology by experimetation to get some conclusion. |
