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...
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...
