ERROR CORRECTION CODE DECODER AND A METHOD THEREOF

An error correction decoder that, if the sum of the number of instances of error data and possible error data is in the range of the error correction capacity of the decoder, recognizes all the data as erasures, and if the sum is not in the range of the error correction of the decoder, recognizes only the error data as erasures. Therefore, the error correction decoder classifies the possible error data as erasures not within the range of the error correction capacity of the decoder and effectively decodes by implementing the error correction.
