Abstract
In an error detection and correction method, when decoding second codewords of doubly encoded information codes, the second codewords, which are considered to have a correlation with the occurrence of burst errors, are classified into groups on the basis of the decoding states of first codewords of the doubly encoded information codes, and the second codewords are decoded sequentially in the order of a group having lower error misdetection probability and on the basis of the decoding states of the second codewords, namely, the error occurrence states, up to that time, thereby enhancing the error detection capability.
