Abstract

We introduce an error correcting 4/6 modulation codes for holographic data storage, and simulate under adding mis-alignment noise. The holographic data storage has two-dimensional intersymbol interference. To increase the channel performance, it is necessary to use modulation code. Furthermore, if the modulation code has trellis structure, error correcting capability is added. The error correcting 4/6 modulation code shows better performance than conventional modulation codes with and without mis-alignment noise.

본 논문은 홀로그래픽 저장장치를 위한 오류 정정 4/6 변조 부호에 대해서 알아보고, 어긋남이 존재하는 상황에서 성능을 알아보았다. 홀로그래픽 저장장치는 2차원 인접 심볼간 간섭이 생기는 채널로, 읽기 성능을 높이기 위해 변조 부호를 사용해야 한다. 이러한 변조 부호에 길쌈 구조가 더해지면 오류 정정 능력을 가지게 된다. 오류 정정 4/6 변조 부호는 기존의 변조 부호보다 성능이 우수하였고, 어긋남에 대해서도 강인한 성능을 보여준다.
