Abstract

PURPOSE:To obtain signal constitution of high correction performance by simple algorithm by adding several fixed check codes to data. CONSTITUTION:Through modulo-2 arithmetic of respective bits of data A to C, check code P is generated 101 and after an excessive code of fixed polarity is added to data A to C, check code Q is generated 102 from results of sequential shifts through modulo-2 arithmetic of each bit. In addition, data A to C and codes P and Q are provided 104 with check codes R1 to R5 for the detection of errors. Consequently, even if errors occur to two out of data A to C and codes P and Q, original data can be restored by remaining signals.
