Abstract
Disclosed is an erasure-based Reed-Solomon code soft-decision decoding method and device, capable of reducing a decoding time while minimizing the effect on error correction performance. The Reed-Solomon code soft-decision decoding device includes an erasure control circuit configured to determine whether a number of errors in a codeword is odd or even, and to provide a key equation solver circuit with a first erasure pattern or a second erasure pattern according to a result of the determining when a decoding failure is detected by a decoding error detection circuit, the first erasure pattern being provided when the number of errors is odd, the second erasure pattern being provided when the number of errors is even.
