<p>A method for decoding a picket code data cluster is disclosed, wherein said picket code data cluster comprises high protective code words and low protective code words. The method comprises steps (a) to (e). In step (a), the high protective code words are decoded so as to generate high protective word erasure indicators showing whether decoding error occurs. In step (b), the high protective word erasure indicators are stored into a memory. In step (c), erasure bits are generated, wherein each erasure bit corresponds to respective ones of the low protective code words if one or more of the high protective word erasure indicators of the high protective code words which are close to said one of the low protective code words shows an error. In step (d), the low protective code words are decoded by using the erasure bits. In step (e), the memory is initialized when another picket code data cluster stars to be decoded.</p> |
