- Abstract
- Storing data into a two dimensional pixel image in the holographic data storage (HDS) imposes new constraints in modulation codes. In this paper, we propose a modulation codeword selection procedure based on integer programming models reducing two-dimensional inter-symbol interference (2-D ISI) and inter-page interference (IPI). We formulated an integer programming model that selects codewords satisfying symbol balance and 3-0 violation constraints. We also develop a cutting plane generating sub- model for generating cuts as needed for large scale implementation. We applied the proposed models to 2/3 and 3/4 4-ary codes and compared its performance. © 2016, ICIC Express Letters Office. All rights reserved.
