Error correction method using reed-solomon code

Abstract From the Canadian patent

In an error correction method using Reed-Solomon code when the error correction is performed by using the result of the multiplication of a syndrome and an error location, another syndrome is added to thereby form a new syndrome. By repetitively executing this procedure the, error vector is obtained by a small number or arithmetic operations relative to a known procedure thereby performing, error correction by the so-called erasure correction technique. Then, by calculating another error vector using the first calculated error vector, the number of arithmetic operation times can be even further reduced.
