Low-complexity multi-intelligent metasurface dynamic threshold phase shift design method

The invention discloses a low-complexity multi-intelligent-metasurface dynamic threshold phase shift design method, belongs to the field of wireless communication, and is used for a communication system in which a transmitting end and a receiving end are respectively provided with a single antenna and deploy a plurality of intelligent metasurfaces, and the wave path of each section of electromagnetic wave from the transmitting end to the receiving end through each intelligent metasurface is calculated; calculating an ideal continuous phase shift of each unit on each intelligent metasurface according to the wave path of the electromagnetic wave; one intelligent metasurface is selected, and the optimal quantization threshold value of the intelligent metasurface is obtained through traversal search; calculating optimal quantization thresholds of other intelligent metasurfaces according to the optimal quantization threshold of the intelligent metasurface and the wave path of the electromagnetic waves passing thro
