METHOD AND DEVICE FOR ERROR CORRECTION

摘要

PROBLEM TO BE SOLVED: To carry out neither unnecessary syndrome operation nor arithmetic processing after syndrome operation. SOLUTION: A format interface 10a decides whether or not an uncorrectable error is included in parallel to the demodulation of receive data and outputs an uncorrectable error detection signal when an uncorrectable error is included. An error and loss correcting circuit 20a decodes error correction including syndrome operation for demodulated data from the format interface 10a and interrupts the syndrome operation when the uncorrectable error detection signal is inputted to quit the error correction.
