Paper Abstract

In volume holographic data storage systems, there are brightness variations across the detected image. An incorrect choice of the threshold can cause significant degradation in the BER. Therefore various modulation codes, including global threshold, local threshold, and equal-weight modulation codes, are proposed for volume holographic data storage systems to improve performance by providing their advantages at the decision stage. Considering about our target and the properties of our holographic data storage system, we select a modulation code for our system and realize it.
