Algorithm 1
Error checking for decoding.
Input: | The frozen nodes set, ; | The probability messages set of the ; | The matrixes, , and ; | Output: | The error indicator vectors set, ; | () Getting with the probability messages set of ; | () Getting with and ; | () for each do | () if then | () Setting the error indicator for each leaf node of to 0; | () end if | () end for | () for each valid of do | () Getting with and ; | () if (11) is satisfied then | () Getting with ; | () else | () Dropping the solution and continuing; | () end if | () end for | () return ; |
