We believe that this work could contribute to the implementation of the nonlinear compensation methods based on perturbation theory. The numerical error of the pre-compensation and the relevance relationship between the original compensation and the post-compensation have been demonstrated in this paper, which could push forward the research of the perturbation-based compensation methods in the coherent fiber communication systems, especially in the unrepeatered systems with Raman
