The decoder is coupled to the erasure flag processor to correct the symbols according to the erasure flags and outputs the corrected symbols. The confidence flag processor is coupled to both the erasure flag processor and the decoder to reset the confidence flag values of the confidence flags according to the erasure flags and the corrected symbols.
