Linear codes over finite chain rings

Nettet1. okt. 2024 · Codes over finite commutative rings have been studied for almost 50 years. The main motivation of studying codes over rings is that they can be associated with codes over finite fields through the Gray map. Recently, most of studies concentrated on codes over finite non-chain ring. Nettet1. feb. 2024 · This Gray map establishes a bridge between the linear codes over finite chain rings and codes (could be non-linear) over finite fields. Our work is particularly …
