摘要

摘要：以智能反射面（intelligent reflecting surface，IRS）辅助的无线携能通信（simultaneous wireless information and power transfer，SWIPT）系统为背景，研究了该系统中基于能效优先的多天线发送端有源波束成形与IRS无源波束成形联合设计与优化方法。以最大化接收端的最小能效为优化目标，构造在发送端功率、接收端能量阈值、IRS相移等多约束下的非线性优化问题，用交替方向乘子法（alternating direction method of multipliers， ADMM）求解。采用Dinkelbach算法转化目标函数，通过奇异值分解（singular value decomposition，SVD）和半定松弛（semi-definite relaxation，SDR）得到发送端有源波束成形向量。采用SDR得到IRS相移矩阵与反射波束成形向量。结果表明，该系统显著降低了系统能量收集（energy harvesting，EH）接收端的能量阈值。当系统总电路功耗为-15 dBm时，所提方案的用户能效为300 KB/J。当IRS反射阵源数与发送天线数均为最大值时，系统可达最大能效。

Abstract

Intelligent reflecting surface (IRS)-assisted simultaneous wireless information and power transfer (SWIPT) system is set as research background.Joint design and optimization of energy-efficiency priority based active beamforming at multi-antenna transmitter and passive beamforming at IRS were investigated.The optimization objective was to maximize minimum energy-efficiency

which was subject to transmitter power control

energy constraint at energy harvesting (EH) receiver and IRS phase shift constraint.Alternating direction method of multipliers (ADMM) was implemented to solve this non-linear non-convex optimization problem.Firstly

the fraction objective function was transformed via Dinkelbach’s approach.Singular value decomposition (SVD) andsemi-definite relaxation (SDR) were applied to obtain active beam forming vector at transmitter.Simulation results indicate that

IRS assisted SWIPT could significantly reduce energy threshold at EH receiver.The achievable energy-efficiency of the proposed strategy is 300 KB/J when total circuit power consumption is -15 dBm.Maximum energy-efficiency can be achieved with the maximum numbers of passive reflecting elements and transmitter antennas.
