METHOD AND DEVICE FOR DECODING REED-SOLOMON (RS) CODE

摘要

The embodiments of the invention disclose a method for decoding an RS code, the method comprising: receiving bit reliability information of the RS code output by a channel, performing a hard decision on the bit reliability information to obtain a hard-decision result value sequence; determining a type of an error of the hard-decision result value sequence according to an initial check array corresponding to an encoding mode of the RS code; according to preset corresponding relationships between types of errors of the hard-decision result value sequence and error-correcting modes capable of correcting the errors, determining an error-correcting mode corresponding to the type of the error of the hard-decision result value sequence, and performing a bit error correction on the hard-decision result value sequence according to the determined error-correcting mode; outputting the hard-decision result value sequence after the bit error correction as a decoding result. The embodiments of the invention also disclose a device for decoding an RS code. By using the invention, the decoding performance of the RS code can be efficiently improved, and the decoding complexity can be reduced.
