Intelligent reflecting surface shift control method, system and equipment

Abstract

The embodiment of the invention discloses an intelligent reflecting surface shift control method, system and equipment, which are applied to the field of communication. Firstly, different phase shift values are set for all reflection units of the intelligent reflection surface, the intelligent reflection surface reflects radio frequency signals under different phase shift value combinations, after a receiving end receives the signals, a phase shift processor determines an optimal phase shift array of the intelligent reflection surface according to statistical characteristics of the received signals, and finally, the phase shift controller sets a phase shift value for each reflection unit of the intelligent reflection surface according to the optimal phase shift array. According to the embodiment of the invention, the operation is simple, the calculation complexity is low, the signal quality of the receiving end can be enhanced or weakened under the condition that the existing communication system architecture and communication protocol do not need to be changed, and the technical bottleneck problem that the traditional intelligent reflection panel phase shift control method depends on channel estimation and complex beam forming calculation is effectively solved.
