Embodiment Construction
[0033] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and implementation examples.
[0034] The present invention proposes a D2D communication system assisted by an intelligent reflecting surface. The system consists of N single-antenna D2D device pairs, K cellular users, a base station, and an intelligent reflector. The intelligent reflective surface includes M passive reflective units and a controller connected to them; wherein, each reflective unit adjusts the amplitude and phase of the incident signal before reflection, and the controller can dynamically adjust the amplitude and phase offset of the reflective unit, intelligently Reconfigure the wireless communication environment to achieve useful signal enhancement and interference suppression.
[0035] Considering a single-antenna base station, assuming that all devices deploy a single antenna, the number of reflection u...
