Finite-dimensional error-correcting code (ECC)[1] 

Description

An error-correcting code defined over a finite alphabet.

Protection

A code corrects errors associated with a noise channel if it is possible to recover any codeword after its coordinates have been changed after going through the channel. More technically, an error-correcting code \((u,\mathcal{E})\) is an encoder function \(u:[1\cdots K]\to[1\cdots N]\) with a set of correctable errors \(E:[1\cdots N]\to [1\cdots M]\) with the following property: there exists a decoder function \(d:[1\cdots M]\to [1\cdots K]\) such that for all \(E\in\cal{E}\) and states \(x\in[1\cdots K]\), \(d(E(e(x)))=x\) [2].

Decoding

Capacity-achieving Guessing Random Additive Noise Decoding (GRAND) [3] (see also [4]).

Notes

The modern theory of error-correcting codes is rooted in the foundational work of C. Shannon [1], but error-correcting codes have been used prior to that work [5].Boolean networks, designed to model gene regulatory networks, generically develop error-correcting codes when they are evolved to perform computations [6].
