Any suggestion is welcome – Math Geek Jan 12 '13 at 15:58
Suggestions: look up the definition of BCH code: look up the definition of dual of a code: look at some other examples where there are proofs that one code is the dual of another. – Gerry Myerson Jan 12 '13 at 19:43

hint: RS codes are the special type of BCH codes,their dual are BCH too and all RS codes are MDS code and the dual of a MDS code is MDS too
