正确答案:C 解析:按照海明的理论,纠错码的编码就是把所有合法的码字尽量安排在n维超立方体的顶点上,使得任一对码字之间的距离尽可能大。如果任意两个码字之间的海明距离是d,则所有少于等于d-1位的错误都可以检查出来,所有少于d/2位的错误都可以纠正。一个自然的推论是,对某种长度的错误串,要纠正它就要用比仅仅...
利用海明码(Hamming Code)纠正单位错,如果有7位信息位,则至少需要加入(8)位冗余位。 A. 2 B. 3 C. 4 D. 5 相关知识点: 试题来源: 解析 C 正确答案:C 解析:信息冗余中的海明码能纠正可能出现的单比特错。假设信息位为k,冗余校验位为r,纠正单比特错需满足2r≥k+r+1的关系。本试题中,k=7,则...

Therefore, ifHHis the parity-check matrix for a codebookCC, then a vectorccin the received code space is a valid codeword if and only if it satisfiescHT=0cHT=0. Consider a vector of received wordr=c+er=c+e, whereccis a valid codeword transmitted andeeis the error introduced by the...
Analog MAP decoder for (8,4) Hamming code in subthreshold CMOS An all-MOS analog tail-biting MAP decoder is presented for an (8,4) Hamming code. The decoder implements a probability propagation algorithm using subthreshold CMOS networks. Physical results verify the expected behavior of the ...
