Abstract

Existing modified Two Dimensional Soft Output Viterbi Algorithm (2D SOVA) for Holographic Data Storage (HDS) uses a 1D SOVA about two different 1D PR targets (vertical and horizontal directions) and changed cost function of the 1D SOVA. In this paper, we propose modified 2D SOVA with 2D PR target and new cost function of the 1D SOVA. The proposed method has a better performance of Bit Error Rate (BER) than the existing method because this cost function is structurally modified from the 2D PR target form.
