A DECODING METHOD AND DEVICE FOR REED-SOLOMON CODE
摘要
<p>A decoding method and a decoding device for Reed-Solomon (RS) code are presented by the invention. The method includes the following steps: A. filling data to be decoded in a byte interleaver in sequence column by column; B. cyclically shifting data in parity region of byte interleaver by row and /or by column, so as to make every row of data in the parity region be the parity data of data in the information region of the byte interleaver in the corresponding row; C. performing RS decoding row by row, and writing the decoded information data in the information region of the byte interleaver in sequence row by row; D. reading out business data from the decoded information data in the information region of the byte interleaver column by column. The method and device present by the invention can achieve best data interleaving effect.</p>
