I have another homework to do, please give me some hints in order to solve this problem:

"Determine whether the dual of an arbitrary BCH code is a BCH code."

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
