PROJECT TITLE :
8/10 two-dimensional modulation code for holographic data storage systems
Holographic information storage (HDS) provides the high storage density and quick data-access rate as a result of of the page-oriented data processing, and by the same reason, the performance of retrieving original user information is principally plagued by 2D intersymbol interference (ISI). An 8/ten 2D modulation code for mitigating a 2D ISI in HDS systems is proposed. The simulation results show that the proposed code provides a gain of roughly vi dB at BER of 10−six compared to the raw signal without encoding. Especially, in comparison to a recently instructed 6/8 modulation code, the proposed theme not solely offers a better code rate, but it conjointly exposes a boost of the system performance under misalignment conditions.
