我们考虑的问题，估计的3D对象的方向与可配置的反向散射标签的协助。我们探讨了设计标签响应代码的想法，以提高方向估计的准确性。为了最小化真实和估计方向之间的差异，我们提出了两个代码设计标准。我们还推导出一个下限的最坏情况下的错误使用Le Cam的方法，并提供了多个场景，包括视线和多路径的仿真结果，比较理论界的设计实现。
We consider the problem of estimating the orientation of a 3D object with the assistance of configurable backscatter tags. We explore the idea of designing tag response codes to improve the accuracy of orientation estimation. To minimize the difference between the true and estimated orientation, we propose two code design criteria. We also derive a lower bound on the worst-case error using Le Cam’s method and provide simulation results for multiple scenarios including line-of-sight only and multipath, comparing the theoretical bounds to those achieved by the designs.
