摘要
本文研究了二元对称信道上，某些BCH码的不可检错误概率．首先得到了几个重要的不等式．然后证明了纠正两个错误二进制本原BCH码的扩展码是最佳检错码．
The unddscted are probablity of smoo BCH codes in binaly symmetric channals is studied.Several importan unequalities are obtalned. Then the extended codes of binary prinmitive BCH codes carecting 2errors are proved to be proper codes for erro deection.
