摘要翻译：
方向调制(DM)是一种基于天线阵列的物理层安全技术，目前在设计中没有考虑极化信息。为了提高信道容量，我们考虑利用极化信息，以相同的方向、相同的频率、不同的极化同时发送两个不同的信号。这两个信号也可以被认为是使用跨越两个极化分集信道的四维(4-d)调制方案的一个复合信号。本文以交叉偶极子阵列为基础，设计了一组公共权系数来实现对这种复合信号的定向调制，并给出了实例来验证所提方法的有效性。

英文摘要：
  Directional modulation (DM) is a physical layer security technique based on antenna arrays and so far the polarisation information has not been considered in its designs. To increase the channel capacity, we consider exploiting the polarisation information and send two different signals simultaneously at the same direction, same frequency, but with different polarisations. These two signals can also be considered as one composite signal using the four dimensional (4-D) modulation scheme across the two polarisation diversity channels. In this paper, based on cross-dipole arrays, we formulate the design to find a set of common weight coefficients to achieve directional modulation for such a composite signal and examples are provided to verify the effectiveness of the proposed method.
