AI Technical Summary
In complex environments, non-line-of-sight interference leads to large deviations in channel parameter estimation and low positioning accuracy. Existing solutions cannot effectively eliminate multipath interference at the physical level.
By actively reshaping the channel through intelligent metasurfaces and projecting channel components using the orthogonal basis matrix of discrete Fourier transform, destructive interference of non-line-of-sight paths is achieved, the physical propagation channel is purified, and positioning accuracy is improved.
It significantly improves positioning accuracy and robustness in complex environments, and achieves high-precision positioning by correcting the initial channel estimation error through an iterative feedback mechanism.
