Finally, we analyze the effect of the proposed optimal de-duplicated (ODD) decoding approach. The results are shown in Tab. We can see that the proposed ODD decoding method consistently outperforms this empirical method. This shows that our proposed method can overcome the sub-optimal problem of the post-de-duplication method.
