Outline of Final Research Achievements

In this study, we propose a new coding and decoding scheme based on Low-Density Parity-Check (LDPC) codes and probabilistic inference to correct insertion, deletion, and substitution (IDS) errors, which are known to occur in DNA storage. Specifically, we developed a design method for irregular LDPC codes for ID+noise errors, a sliding window-based error correction method, and a nonbinary LDPC coding method to correct position errors in racetrack memory (RM). These methods have improved the reliability and efficiency of IDS error correction codes, taking a step toward practical application. Additionally, the delayed coding (DC) scheme enables high performance while reducing computational costs.
