WebConsider a linear [n,k,d]_q code C. We say that that i-th coordinate of C has locality r, if the value at this coordinate can be recovered from accessing some other r coordinates of C. Data storage applications require codes with small redundancy, low locality for information coordinates, large distance, and low locality for parity coordinates. In this paper we carry … Web3 de dez. de 2024 · It is well known that RS(A(Fq),m)⊥=RS(A(Fq),q−m−2) and that the locality of RS codes is r0=k. 4.1. LREDC’s from RS codes Let P⊆A(Fq). Consider the code C=RS(P,k−1) of length n=#P and dimension k≤n−2.

In this case, the locality can be classified into two cases: “information locality r ” if all information symbols have locality r, and “all-symbol locality r ” if all symbols have locality r. fliss mercer telford
