Abstract

In this paper, we study skew cyclic codes with arbitrary length over the ring R=Fp+uFpR=\mathbb{F}_{p}+u\mathbb{F}_{p} where pp is an odd prime and % u^{2}=0. We characterize all skew cyclic codes of length nn as left % R[x;\theta ]-submodules of Rn=R[x;θ]/xn1R_{n}=R[x;\theta ]/\langle x^{n}-1\rangle . We find all generator polynomials for these codes and describe their minimal spanning sets. Moreover, an encoding and decoding algorithm is presented for skew cyclic codes over the ring RR. Finally, based on the theory we developed in this paper, we provide examples of codes with good parameters over FpF_{p} with different odd prime p.p. In fact, example 25 in our paper is a new ternary code in the class of quasi-twisted codes. The other examples we provided are examples of optimal codes.
