Abstract

The invention discloses a SWIPT system performance optimization method and system based on intelligent reflecting surface assistance, and the method comprises the steps: decoding information and collecting energy through a power divider at the same time, introducing RIS to compensate the serious path loss and shadow fading, and employing IGS to compensate the loss caused by unavoidable asymmetric hardware distortion; the objective is to maximize the minimum achievable rate of a user and a rate energy domain with weight by jointly optimizing active and passive beamforming vectors and a power distribution coefficient under the constraint of AP power budget and energy service quality requirements of the user. According to the method disclosed by the invention, the influence of the HWI and the interference among the users are compensated by adopting an asymmetric Gaussian signal scheme, the maximum rate and the minimum rate are remarkably improved, and the performance optimization problem of the SWIPT system assisted by the RIS with the HWI is solved.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a method and system for optimizing the performance of a SWIPT system based on the assistance of an intelligent reflection surface. Background technique [0002] Reconfigurable smart surfaces (RIS) stand out among new technologies due to their unique characteristics of low cost, low energy consumption, programmability, and easy deployment. RIS is an artificial electromagnetic surface structure with programmable electromagnetic properties. RIS consists of a large number of passive reflective elements, each of which is a reconfigurable scatterer (eg, positive intrinsic negative (PIN) diodes, varactor tuned resonators, liquid crystals, and microelectromechanical systems (MEMS) technology). Through a central controller, each reflective element can independently control the amplitude and phase of the incident electromagnetic wave (ie add a different time del...
