ECC for DNA Storage

Specific Topics on ECC for DNA Storage

  1. Error Correction Code (ECC) Converted from Classical Codes for DNA Storage

  2. New Desing of Insertion/Deletion Codes to Satisfy GC-Content and Homopolymer Run

  3. LDPC Code Design for DNA Storage

  • Basic of DNA Storage: Wikipedia link (Properties, History, References)


  • Comparison Between DNA Storage and Other Storage Systems

  • LLR Calculation of LDPC Codes for DNA Storage

  • System Model

  • Purpose

    1. Statistics of DNA storage channels have not fully been analysed yet.

    2. Decoding of LDPC codes needs log-likelihood ratio (LLR) to compute inputs of their variable nodes.

    3. We propose two strategies: S1) direct scaling LLRs and S2) scaling pairwise substitution error rates.

  • Performance Comparison

    1. Reading cost (Rread) vs. Number of read to be successful decoding

    2. At eight experiments, there are gains of the proposed system.
