报告摘要:

This paper proposes to construct binary array codes from non-binary codes by binary matrix dispersion. Thanks to their low-density and quasi-cyclic (QC) generator matrices, the proposed codes enjoy low encoding complexity, about 1/(m+1) of the XOR operations used in their counterparts over GF(2m). Their maximum distance separable (MDS) property and repair can be efficiently analyzed via matrix transformation. The MDS property is ensured by introducing Vandermonde upper triangular form and pre-processing. Moreover, the efficient repair can be guaranteed by applying a matrix mapping called all-one superposition on the associated matrices. undefinedysis indicates that their code rate and repair ratio asymptotically approach those of their non-binary counterparts.
