A Family of Codes With Locality Containing Optimal Codes
Bruno Andrade, Cícero Carvalho, Víctor Neumann, Antônio Cláudio Paschoarelli Veiga · IEEE Access · 2022
Locally recoverable codes were introduced by Gopalanet al.in 2012, and in the same year Prakashet al.introduced the concept of codes with locality, which are a type of locally recoverable codes. In this work we introduce a new family of codes with locality, which are subcodes of a certain family of evaluation codes. We determine the dimension of these codes, and also bounds for the minimum distance. We present the true values of the minimum distance in special cases, and also show that some elements of this family are “optimal codes”, as defined by Prakashet al.
