This contribution is concerned with codes formed by generalising (or iterating) one or more component codes into arrays in (conceptually) two or more dimensions (which need not be orthogonal). Array codes can be used for multiple randan-error detection and correction, for burst-error detection ...
本文研究了一类重要的有结构LDPC码——阵列码(array codes)的校验矩阵$H(r,q)$。在压缩感知理论中,测量矩阵的spark定 … www.paper.edu.cn|基于4个网页 2. 阵码 另一类低密度奇偶校验码和我们熟知的阵码(Array codes)一样,其校验矩阵是由一些小的循环置换矩阵组成,且覆盖一大类不同码 … ...
typecode参数的值是一个字符,这个字符被称为类型码,其代表一种类型限制,所有的类型码可以使用array.typecodes查看: import array print(array.typecodes) # bBuhHiIlLqQfd 在上述的例子中,返回值中的每个字符都是一个类型码,那么这些类型码都是什么意思呢? 类型码 C 类型 Python 类型 以字节表示的最小尺寸 'b...
Two families of binary linear multiple-burst-correcting array codes are presented. The codes consist of all possible n 1 × n 2 arrays over GF(2), where the columns have even parity and the rows belong to any given code of length n 2 and minimum distance 2 t . It is shown that if...

Solved: Hello all, I'm attempting to automatically compile an array of domain codes for comparison when deciding how to visualize a layer. So this is what I've got
4) cyclic array codes 循环阵列码 1. In this paper,we study cyclic array codes by using algebraic tools. 本文用代数观点来研究循环阵列码,证明了一般的阵列码是一些极小循环阵列码的直和,并且对极小循环阵列码给出了明确的刻画。5) erasure array codes 阵列纠删码...
