On \(Q\)-ary images of self-dual codes
The author presents some characterization of \(q\)-ary images of systematic codes and proves that every self-dual code over the finite field \(GF(q^ m)\) has a \(q\)-ary image which is also a self-dual code. Some constructions of symmetric bases together with several examples are given at the end.
