Concerns have been raised about our recently published article on the fixed region beamforming using frequency diverse subarray for secure mmWave wireless communications. In a comment, the authors thought our precoding vector normalization method of the sidelobe randomization scheme has a flaw and proposed a non-physical-layer-security-oriented (non-PLS-oriented) normalization method by keeping the norm of the steering vector as a unit. However, we believe our PLS-oriented normalization method of the transmit beamforming vector is correct and reasonable from the PLS perspective, i.e., we hope to keep the target use’s beampattern gain unit. In this rebuttal, we further clarify and justify our scheme to show its correctness. In addition, we also present a generalized normalization method to compare our proposed PLS-oriented scheme and the non-PLS-oriented scheme in the comment to offer useful insights.

驳斥“关于“使用分频子阵列进行安全MmWave无线通信的固定区域波束成形的评论””

对于我们最近发表的有关使用固定频率毫米波无线通信使用频率变化子阵列的固定区域波束成形的文章，已经引起了人们的关注。在评论中，作者认为我们的旁瓣随机化方案的预编码向量归一化方法存在缺陷，并通过将转向向量的范数保持为一个单位。但是，我们认为从PLS角度看，面向PLS的发射波束成形矢量归一化方法是正确和合理的，即我们希望保持目标用户的波束图增益单位。在这一反驳中，我们进一步澄清和证明我们的方案以显示其正确性。此外，
