Abstract: PURPOSE: An error control code generating system and a method thereof are provided to quality of reconstructed information by transmitting information based on a generated error control code. CONSTITUTION: A connected number distribution pair calculation part(110) calculates connected number distribution pairs about vectors including integers less than the maximum connected number of variable nodes to element. The rate calculation part(120) calculates rate between an error probability of an arbitrary connected number and an average error probability of a code word with respect to the connected number distribution pairs. A vector selecting part(130) selects a vector corresponding to the connected number distribution pair with the largest rate as a parameter. A code generating part(140) generates an error control code based on the vector selected as a parameter.
