Webically the minimum stopping set size and cooperative locality of the codes. This paper is organized as follows. Section2 presents relevant background. We derive bounds on the minimum stopping set size and cooperative locality of regular hypergraph codes in Sect.3. In Sect.4, we show how to construct a

Web28 de ago. de 2024 · The locality constraints of a linear code are stipulated by a matrix of 's and 's (which we call a "stencil"), whose rows correspond to the local parity checks (with the 's indicating the support of the check). The visible rank of is the largest for which there is a submatrix in with a unique generalized diagonal of 's.

Using our structure theorem, we obtain a tight bound for the locality of parity symbols possible in such codes for a broad class of parameter settings. We prove that there is a tradeoff between having good locality for ...
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 …
