Two-dimensional Interleaving Scheme for Volume Holographic Data Storage
体全息存储中二维交错编码技术的研究及实现

In order to defend burst errors and random errors in the volume holographic storage system, information is encoded in the form of binary data pages which include modulation channel coding, data interleaving and error correction. A two-dimensional interleaving technique that can correct two-dimensional bursts (or clusters) of errors for volume holographic storage is presented. By adopting high speed FPGA, two-dimensional block-interleaved RS(255,223) codes are created based on t-interleaved arrays of integers, which defined by the property that every connected component of area t consists of distinct codewords.
