In coding theory, group codes are a type of code. Group codes consist of n linear block codes which are subgroups of Gⁿ, where G is a finite Abelian group. A systematic group code C is a code over Gⁿ of order |G|ᵏ defined by n-k homomorphisms which determine the parity check bits. The remaining k bits are the information bits themselves.
