The Optimal Asymptotic Rate of Generalized Covering Codes

Hengzhuo Li, Chong Shangguan, Hengjia Wei

Let $G_{q}$ be an alphabet of size $q \geq 2$ . We determine the optimal asymptotic rate of generalized covering codes $C \subseteq G_{q}^{n}$ , whose covering centers in $G_{q}^{t \times n}$ ar…

Sharp Bounds and New Constructions for Single-Error Detection and Correction in Analog Codes

Hengzhuo Li, Zhengjie Jian, Xin Wang +1

We study single-error detection and correction for analog codes over $R$ . The key performance measures are the parameters $Γ_{1} (C)$ and $Γ_{2} (C)$ , which…
