摘要: The invention provides a method for updating check-node of low-density parity-check (LDPC) codes decoder. The method comprises the following steps: First of all, sort all data that are input into the check-node of LDPC codes decoder to find a minimum absolute value and a second minimum absolute value. Secondly, compare each of all the data to both of the minimum absolute value. If the compared data is equivalent to the current minimum absolute value, the compared data is updated by the secondary minimum absolute value. Otherwise, the compared data is updated by the minimum absolute value.
