Code in permutations[13]

Alternative names: Permutation-based code.

Description

Encodes codewords into permutations of \(n\) objects. Permutation group elements can be mapped to inversion vectors [4] over a mixed alphabet.

Protection

Protects against errors in the Kendall tau distance on the space of permutations. The Kendall distance between permutations \(\sigma\) and \(\pi\) is defined as the minimum number of adjacent transpositions required to change \(\sigma\) into \(\pi\). Various bounds have been developed [4,5], including LP bounds [6]. The mapping to inversion vectors is not distance preserving, but the \(\ell_1\) distance between inversion vectors is a lower bound on the Kendall tau distance [4].

Other distances include the Ulam distance [7].

Rate

Asymptotically good codes in the Ulam metric exist [8].

Notes

Review of parallels between linear binary codes and permutation groups [9].

Cousins

  • Convolutional code— Convolutional codes in permutations have been constructed [10].
  • Mixed code— Permutation group elements can be mapped to inversion vectors [4] over a mixed alphabet.
