$\mathsf{GC+}$ Code: a Short Systematic Code for Correcting Random Edit Errors in DNA Storage (2402.01244v3)

Abstract: Storing digital data in synthetic DNA faces challenges in ensuring data reliability in the presence of edit errors -- deletions, insertions, and substitutions -- that occur randomly during various phases of the storage process. Current limitations in DNA synthesis technology also require the use of short DNA sequences, highlighting the particular need for short edit-correcting codes. Motivated by these factors, we introduce a systematic code designed to correct random edits while adhering to typical length constraints in DNA storage. We evaluate the performance of the code through simulations and assess its effectiveness within a DNA storage framework, revealing promising results.
