Abstract: An MAP algorithm-based Turbo decoding method and apparatus. The method includes: iteratively estimating an information symbol by using an MAP algorithm, acquiring an α and β window boundary values of each sliding window by means of window boundary value inheritance, acquiring an α block boundary value and β block boundary value of each sub-block by means of block boundary value inheritance, and recursively calculating posterior probability Log Likelihood Ratio (LLR) values of a whole window and a whole block according to the α boundary values and the β boundary values (101); and performing decoding decision according to the LLR values (102).
