Abstract

N symbols of a code word inputted from a transmission line and constituting an error detection and/or correction code are divided into i symbol groups, i coefficient groups are generated by dividing n coefficients of a check matrix into i groups, the n coefficients being used for calculation with each code word, and an error of the code word is detected and/or corrected by using a syndrome obtained by adding the calculation results between the i symbol groups and the i coefficient groups, where i is an integer equal to or larger than 2, and n is an integer equal to or larger than i.
