UAV搭载STAR-RIS辅助的空地协同通信性能优化
Optimization of air-ground cooperative communication performance for UAV-mounted STAR-RIS
摘要
Abstract
In the scenario of air-ground cooperative communication with unmanned aerial vehicle(UAV)-mounted simul-taneously transmitting and reflecting reconfigurable intelligent surface(STAR-RIS),the coupling between STAR-RIS unit energy allocation and total power constraints leads to mutual restrictions between system capacity and user cover-age.During window rolling,UAV position deviations caused by wind disturbance and cascaded channel state informa-tion(CSI)time variations due to small-scale fading result in dynamic drift of the optimal capacity-coverage trade-off so-lution.To address this,a multi-objective optimization algorithm based on trajectory pipeline constraints was proposed.A slow-timeslot rolling window was introduced to evaluate the trade-off solution drift problem,where the control layer gen-erated executable UAV position sequences via pipeline constraints.The optimization layer jointly configured STAR-RIS amplitude-phase and user power allocation,employing a decomposition-based multi-objective differential evolution algo-rithm to approximate the Pareto trade-off frontier.Simulation results demonstrate that the proposed method achieves su-perior and stable system trade-off performance compared to baseline schemes while ensuring trajectory feasibility,and further reduces online computational overhead through a population inheritance mechanism.关键词
