Everything about Locally decodable code

Type of error-correcting code

A locally decodable code (LDC) is an error-correcting code that allows a single bit of the original message to be decoded with high probability by only examining a small number of bits of a possibly corrupted codeword. This property could be useful, say, in a context where information is being transmitted over a noisy channel, and only a small subset of the data is required at a particular time and there is no need to decode the entire message at once. Locally decodable codes are not a subset of locally testable codes, though there is some overlap between the two. Wikipedia →
