Abstract
We present a new method to obtain cyclic sub-codes of algebraic geometric codes using their automorphisms. Automorphisms of algebraic geometric codes from F.K. Schmidt curves are proposed. We present an application of this method in designing frequency hopping sequences for spread spectrum systems. Algebraic geometric codes can provide sequences longer (better randomness) than the ones from Reed-Solomon codes.
