码-综述(MDS码及Singleton Bound的证明)

我的研究方向是通信编码理论,上层建筑是分布式存储中的编码方案,所以对于各类码要非常的熟悉,接下来会将一些手记记录下来。 (前置知识:有限域) (研究的细分领域:信道编码 -》 差错控制编码 -》 分组码/卷积码 -》 分组码 -》 线性分组码 ) 1.码的定义 Fq是一个有限域,Fqn是Fq上的长为 ......

lower_bound( )和upper_bound( )的常见用法

lower_bound()和upper_bound( )都是利用二分查找的方法在一个排好序的数组中进行查找的。 lower_bound(begin,end,num):从数组的 begin 位置到 end-1 位置二分查找第一个大于或等于 num 的数字,找到返回该数字的地址,不存在则返回 end。通 ......
