Spherical code whose codewords are scaled versions of points on a lattice. Each code is constructed by normalizing a set of lattice vectors in one or more shells, i.e., sets of lattice points lying on a hypersphere.
See [2; Ch. 10] for tables of lattice-shell codes.
- Lattice-based code — Lattice-shell codes consists of lattice points that have been normalized.
- Cyclic code — Lattice-shell codewords are often permutations of a particular set of reference vectors, meaning that a cyclic permutation of a codeword yields another codeword.
