Research on boosting self-sustainability for RIS-aided multi-cluster wireless powered communication networks

Tongxin xuebao
The performance maximization was investigated in a reconfigurable intelligent surface (RIS) assisted multi-cluster wireless powered communication network (WPCN). To enhance the self-sustaining capability of the network, the signal-to-noise ratio (SNR) of
