3.8 考虑(23,12,7)二元码。

证明若它被用在一个比特错误概率为
p=0.01的二元对称信道(BSC )中,字错误概率将约为0.00008. 证明:由于(23,12,7)二元码为最优线性码,且有:

故可设计一(23,12,7)二元线性码使其陪集首分别为汉明
重量为0,1,2,3的所有23位码字。

则可计算此线性码通过二元对称信道(BSC )的字错误概率为:

(1) 求奇偶校验矩阵。

(2) 这个码能检测多少个错? (3) 这个码能纠多少个错? (4) 这个码能纠多少个删除? (5) 这是个完备码吗?

(2) 由奇偶校验矩阵H 可得这个码的最小距离为d=3. 检错能力:12t d ≤-=

即这个码至少能纠正所有与许用码距离为1的错误模式。

(4) 设发生r 个位删除,t 为纠正的位数
