摘要
指出了教材《通信原理》在纠检错编码定理证明中存在的问题,应用n维空间的概念,将码字与n维空间中的点一一对应,并利用这种对应关系,对纠检错编码定理给予了新的证明,完善了差错控制编码理论.
The paper points out the problem in proving the law of error correcting or checking codes, and gives the latest proof to the law. The proof uses the one-to-one mapping between a code word and a point of n dimension. This research makes some additional contribution to the theory of error control coding.
