Bianca S. de C. da Silva, Pedro H. C. de Souza, Luciano L. Mendes

AI总结:

本文通过案例研究验证了神经网络在OFDM系统中降低PAPR的有效性,并强调了数据集泛化在模型鲁棒性和实用性中的重要性。

摘要:

在[1]中,我们介绍了一种设计用于降低OFDM系统PAPR的神经网络。然而,原始研究未包含明确的泛化测试以评估该神经网络在未见数据上的表现,这阻碍了对模型鲁棒性和在多样化场景中应用的全面评估。为填补这一空白,我们进行了额外的泛化评估,其结果呈现在本案例研究中。这些结果既补充又完善了[1]中报告的原始分析。最重要的是,初始研究的总体结论仍然有效:该神经网络仍能将PAPR水平降低到期望的参考值,同时计算成本更低,证实了所提出方法在更广泛泛化设置中的有效性和实用性。

英文摘要:

In [1], we introduced a NN designed to reduce the PAPR in OFDM systems. However, the original study did not include explicit generalization tests to assess how well the NN would perform on previously unseen data, which prevented a comprehensive evaluation of the model's robustness and applicability in diverse scenarios. To address this gap, we conducted additional generalization assessments, the results of which are presented in this case study. These results serve both to complement and to refine the original analysis reported in [1]. Most importantly, the overall conclusions of the initial study remain valid: the NN is still able to reduce the PAPR level to a desired reference value, also with a lower computational cost, confirming the effectiveness and practical applicability of the proposed method across a more generalized setting.
