Twisted skew $G$-codes (2212.13190v1)
Published 26 Dec 2022 in cs.IT, math.CO, math.IT, and math.RA
Abstract: In this paper we investigate left ideals as codes in twisted skew group rings. The considered rings, which are often algebras over a finite field, allows us to detect many of the well-known codes. The presentation, given here, unifies the concept of group codes, twisted group codes and skew group codes.
