轨道角动量作为一种提高信道容量的潜在技术，在无线电领域得到了发展。本文提出了一种新的无线电涡旋多输入多输出（RV-MIMO）系统，以提供高容量的自由空间。特别是，所提出的系统的涡流通道建模。基于该模型，推导出最佳涡流相位，从而得到所提出的RV-MIMO系统的最佳容量。仿真结果表明，所提出的RV-MIMO系统可以获得更高的容量比MIMO系统在自由空间。
As a potential technique to improve channel capacity, orbital angular momentum has been developed in the radio field. In this paper, a novel radio vortex-multiple-input multiple-output (RV-MIMO) system is proposed to provide high capacity in free space. In particular, the vortex channel of the proposed system is modeled. Based on this model, the optimal vortex phase is derived, which results in the optimal capacity of the proposed RV-MIMO system. Simulation results show that the proposed RV-MIMO system could achieve higher capacity than the MIMO system in free space.
