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.
