论文摘要
我们建议一种针对视线环境的新型可重构智能表面（RIS）编码的信息传输方案。用数据喂养的RI通过执行新型的差异极化移动键合，调节散射波的极化状态（SOP）发出的波浪的信息。特别是，该信息是在两个连续的散射插槽上的SOP更改中编码的。所提出的方案对无线通道中的SOP波动免疫，该方案允许在接收器处进行非连锁检测。
We propose a novel reconfigurable intelligent surface (RIS) encoded information transmission scheme for a line-of-sight environment. A RIS fed with data modulates the information on impinging waves emitted from an external source in the states of polarization (SoP) of the scattered waves by performing a novel differential polarization shift keying. In particular, the information is encoded in the change of the SoP over two successive scattering slots. The proposed scheme is immune to the SoP fluctuations in the wireless channel which allows for non-coherent detection at the receiver.
