Abstract:According to the multiple-input single-output(MISO)network with simultaneous wireless information and power transfer(SWIPT) system, the hybrid beamforming(BF)design based on a reconfigurable intelligent surface(RIS)is studied, where the digital BF is achieved by the base-station(BS)and the analog BF is realized by the RIS with phase shifters. In order to improve the spectrum efficiency of system, a sum rate maximization(SRM)problem of multi receiver information is built to the alternating optimization(AO)and penalty concave convex procedure(PCCP)method are used to transform the nonconces optimization problem into a convex one, then an iterative algorithm based on joint optimization is proposed to obtain the hybrid BF vectors and the power splitting(PS)ratios. The simulation results verify that the proposed scheme can effectively improve the sum-rate performance of the receiver of the system.
