摘要

涡旋电磁波模态的精确测量是涡旋电磁波解调的基础。然而，旋涡电磁波的空心发散特性使得传统的全孔径接收模态测量方法难以在实际中应用。采用部分孔径接收的模式测量方法虽然可以节省空间资源，但会导致解调性能的下降。考虑旋涡电磁波孔径的对称性，提出了一种改进的虚拟全孔径接收模态测量方法。仿真结果表明，采用该方法可以实现低空间资源成本和低误码率的涡流电磁波解调。此外，与现有的部分孔径接收模式测量方法相比，该方法具有更好的通信性能。

Enhanced Mode Measurement of Vortex Electromagnetic Wave Based on Aperture Symmetry

The accurate mode measurement of the vortex electromagnetic wave is the basis of the demodulation of vortex electromagnetic waves. However, the hollow divergence characteristic of the vortex electromagnetic wave makes the traditional mode measurement method with full aperture reception difficult to apply in practice. Although the mode measurement method with partial aperture reception can save space resources, it leads to the degradation of demodulation performance. Considering the aperture symmetry property of vortex electromagnetic waves, an improved mode measurement method with virtual full aperture reception is proposed. Simulation results show that low space resource cost and low bit error rate can be achieved by employing the proposed method for the demodulation of vortex electromagnetic waves. In addition, compared with existing mode measurement methods with partial aperture reception, the proposed method has better communication performance.
