Improved constructions of secondary structure avoidance codes for DNA sequences

Hui Chu, Chen Wang, Yiwei Zhang

In a DNA sequence, we have the celebrated Watson-Crick complement $T = A$ , $A = T$ , $C = G$ , and $G = C$ . Given an integer $m \geq 2$ , a secondary…

Coding schemes for locally balanced constraints

Chen Wang, Ziyang Lu, Zhaojun Lan +2

Motivated by applications in DNA-based storage, we study explicit encoding and decoding schemes of binary strings satisfying locally balanced constraints, where the $(ℓ, δ)$ -loca…
