Robust Beamforming Design and Time Allocation for IRS-Assisted Wireless Powered Communication Networks
IEEE Transactions on Communications(2022)
摘要
In this paper, a novel intelligent reflecting surface (IRS)-assisted wireless powered communication network (WPCN) architecture is proposed for power-constrained Internet-of-Things (IoT) smart devices, where IRS is exploited to improve the performance of WPCN under imperfect channel state information (CSI). We formulate a hybrid access point (HAP) transmit energy minimization problem by jointly op...
