具有随机矩阵的线性局部可修码

Linear Locally Repairable Codes with Random Matrices

Toni Ernvall, Thomas Westerbäck, Camilla Hollanti

摘要:

本文研究了具有全符号局部性的局部可修码。提出了修改现有代码的方法。此外,它表明,具有高概率,一个随机矩阵与几个额外的列,保证局部性,是一个生成矩阵的局部可修代码具有良好的最小距离。这个证明也给出了一个构造性的方法来寻找局部可修码。

英文摘要:

In this paper, locally repairable codes with all-symbol locality are studied. Methods to modify already existing codes are presented. Also, it is shown that with high probability, a random matrix with a few extra columns guaranteeing the locality property, is a generator matrix for a locally repairable code with a good minimum distance. The proof of this gives also a constructive method to find locally repairable codes.
