On the locality of codeword symbols in non-linear codes
نویسندگان
چکیده
Consider a possibly non-linear (n,K, d)q code. Coordinate i has locality r if its value is determined by some r other coordinates. A recent line of work obtained an optimal trade-off between information locality of codes and their redundancy. Further, for linear codes meeting this trade-off, structure theorems were derived. In this work we give a new proof of the locality / redundancy trade-off and generalize structure theorems to non-linear codes.

On Locally Decodable Index Codes
Index coding achieves bandwidth savings by jointly encoding the messages demanded by all the clients in a broadcast channel. The encoding is performed in such a way that each client can retrieve its demanded message from its side information and the broadcast codeword. In general, in order to decode its demanded message symbol, a receiver may have to observe the entire transmitted codeword. Que...
متن کاملOn taking advantage of multiple requests in error correcting codes
In most notions of locality in error correcting codes—notably locally recoverable codes (LRCs) and locally decodable codes (LDCs)—a decoder seeks to learn a single symbol of a message while looking at only a few symbols of the corresponding codeword. However, suppose that one wants to recover r > 1 symbols of the message. The two extremes are repeating the single-query algorithm r times (this i...
متن کاملLocally Updatable and Locally Decodable Codes
We introduce the notion of locally updatable and locally decodable codes (LULDCs). In addition to having low decode locality, such codes allow us to update a codeword (of a message) to a codeword of a different message, by rewriting just a few symbols. While, intuitively, updatability and error-correction seem to be contrasting goals, we show that for a suitable, yet meaningful, metric (which w...
متن کاملCombinatorial Alphabet-Dependent Bounds for Locally Recoverable Codes
Locally recoverable codes (LRC) have recently been a subject of intense research due to the theoretical appeal and their applications in distributed storage systems. In an LRC, any erased symbol of a codeword can be recovered by accessing only few other symbols. For LRC codes over small alphabet (such as binary), the optimal rate-distance trade-off is unknown. We present several new combinatori...
متن کاملA Bound on Rate of Codes with Locality with Sequential Recovery from Multiple Erasures
An [n, k] code C is said to be locally recoverable in the presence of a single erasure, and with locality parameter r, if each of the n code symbols of C can be recovered by accessing at most r other code symbols. An [n, k] code is said to be a locally recoverable code with sequential recovery from t erasures, if for any set of s ≤ t erasures, there is an s-step sequential recovery process, in ...
