摘要
在轨道角动量（OAM）复用中采用极化技术可以抑制波束发散，因为使用了较低的 OAM 模式，从而延长了链路距离。在本研究中，我们研究了在总发射功率和天线元件总数相同的限制条件下，多输入多输出（MIMO）对极化 OAM 复用的有效性。为了评估极化和 MIMO 对系统容量的综合影响，我们进行了计算机模拟。此外，我们还研究了只有较低 OAM 模式可用时的系统容量，并与没有模式限制的情况进行了比较。我们的研究结果为了解使用极化和 MIMO 进行 OAM 复用的潜在优势提供了宝贵的见解。
Effectiveness evaluation of MIMO in polarized OAM multiplexing
Adopting polarization for orbital angular momentum (OAM) multiplexing can suppress beam divergence because of using the lower OAM modes, which leads to extending the link distance. In this study, we investigate the effectiveness of multiple-input multiple-output (MIMO) on the polarized OAM multiplexing under the restriction of the same total transmit power and total number of antenna elements. To evaluate the combined effects of polarization and MIMO on system capacity, we conducted computer simulations. Moreover, we investigate the system capacity when only lower OAM modes are available, and compare it with the case without mode limitations. The results of our study provide valuable insights into the potential benefits of using polarization and MIMO for OAM multiplexing.
