Efficient Balanced Code Using Viterbi Algorithm and Section Division for Holographic Data Storage

概要

論文の詳細を見る
We propose an error correctible balanced code for holographic data storage. As the transitions of a message word are considered and parity bits that check for errors in the section are appended on encoding, we can decode message words with the Viterbi algorithm and correct errors. The effectiveness of the proposed method is validated by numerical simulations and experiments. An improvement in bit error rate (BER) is achieved.
