List-decodable Codes for Single-deletion Single-substitution with List-size Two

Wentu Song, Kui Cai, Tuan Thanh Nguyen

In this paper, we present an explicit construction of list-decodable codes for single-deletion and single-substitution with list size two and redundancy 3log n+4, where n is the bl…

Systematic Single-Deletion Multiple-Substitution Correcting Codes

Wentu Song, Nikita Polyanskii, Kui Cai +1

Recent work by Smagloy et al. (ISIT 2020) shows that the redundancy of a single-deletion -substitution correcting code is asymptotically at least , where…

Coded Caching with Polynomial Subpacketization

Wentu Song, Kui Cai, Long Shi

Consider a centralized caching network with a single server and users. The server has a database of files with each file being divided into packets ( is known as sub…

Some new Constructions of Coded Caching Schemes with Reduced Subpacketization

Wentu Song, Kui Cai, Long Shi

We study the problem of constructing centralized coded caching schemes with low subpacketization level based on the placement delivery array (PDA) design framework. PDA design is a…

Dynamic Programming for Sequential Deterministic Quantization of Discrete Memoryless Channels

Xuan He, Kui Cai, Wentu Song +1

In this paper, under a general cost function , we present a dynamic programming (DP) method to obtain an optimal sequential deterministic quantizer (SDQ) for -ary input discr…

Sequence-Subset Distance and Coding for Error Control in DNA-based Data Storage

Wentu Song, Kui Cai, Kees A. Schouhamer Immink

The process of DNA-based data storage (DNA storage for short) can be mathematically modelled as a communication channel, termed DNA storage channel, whose inputs and outputs are se…
