METHOD AND DEVICE FOR GENERATING PARITY INSPECTION MATRIX, METHOD FOR CORRECTING CODED BIT STRING BY USING ERROR DETECTION CODE, COMPUTER PROGRAM, DEVICE FOR DETECTING ERROR STIPULATED BEFOREHAND AND DEVICE FOR CODING BIT STRING

摘要

PROBLEM TO BE SOLVED: To provide a parity inspection matrix generated so as to detect an error stipulated beforehand in the coded string of a bit. SOLUTION: The column of a matrix is generated by selecting a value to an element in the column, processing the error stipulated beforehand by the selected value and generating a syndrome. The selected value is allocated to the column of the parity inspection matrix in the case that the element of the syndrome is provided with the value for indicating the error stipulated beforehand.
