Abstract
Holographic data storage system is affected by two dimensional intersymbol interference and inter-page interference. Especially, for multi-level holographic data storage system, since one pixel contains more than 1 bit, the system is more vulnerable to the error. In this paper, we propose a 2/3 modulation code for 4-level holographic data storage system. The proposed modulation code with error correcting capability could be compensated these interferences. Also, in this paper, we proposed a Viterbi decoder for 2/3 modulation code. The proposed Viterbi decoder eliminates unnecessary calculation. As a result, proposed 2/3 modulation code and Viterbi decoder has shown better performance than conventional one.
