An error detection code or an error correcting code or a combination of both which is particularly suited to the correction of burst error or errors that are strongly correlated.
A popular Reed-Solomon code is RS(255,223) with 8-bit symbols. Each codeword contains 255 code word bytes, of which 223 bytes are data and 32 bytes are parity. For this code:
n = 255, k = 223, s = 8
2t = 32, t = 16
The decoder can correct any 16 symbol errors in the code word: i.e. errors in up to 16 bytes anywhere in the codeword can be automatically corrected.
