Abstract

In this paper, we introduce modified parity coding methods to reduce the errors caused by spatial beam intensity variations in a holographic data storage system. We explained the encoding and decoding process of the conventional parity coding and the modified parity coding techniques. We compared the bit-error-rate (BER) performances of the conventional parity coding and the modified parity coding techniques from experimental evaluation.

본 논문에서는 홀로그래픽 데이터 저장시스템에서 발생되는 공간적 빔 세기의 불 균일성 때문에 발생되는 에러를 줄이기 위한 수정된 패리티 코딩기법들을 소개한다. 일반적인 패리티 코딩과 수정된 패리티 코딩 기법들에 대한 인코딩과 디코딩 방법에 대해 설명하였으며, 실험결과로부터 패리티 코딩과 수정된 패리티 코딩기법들의 bit-error-rate(BER)성능을 비교하였다.
