Reed–Solomon Volumetric Coding with Matched Interleaving for Holographic Data Storage

Abstract

For various error patterns, including random errors, burst errors, and inhomogeneously distributed errors, in the holographic data storage (HDS) channel, a Reed–Solomon volumetric coding with matched interleaving (RSVC-MI) scheme is proposed in this paper. The RSVC-MI scheme combines the advantages of the RSVC scheme and the matched interleaving scheme, makes full use of the priori knowledge of the error patterns in the HDS channel, distributes errors more uniformly, and decodes data iteratively in three dimensions. It is able to eliminate the influences of non-uniform distribution of errors within a page and across pages, overcome the effects of burst errors, correct random errors, and effectively reduce the symbol error rate (SER) of the HDS channel.
