摘要
Abstract
To enhance the global coverage capability of wireless networks,STAR-RIS is proposed as a novel RIS architecture.For the requirements of communication,sensing and computation in future 6G networks,this paper investigates the STAR-RIS-assisted integrated sensing,communication and computation(ISCC)system.The objective is to jointly optimize the active and passive beamforming as well as computing resource allocation to improve energy efficiency of the ISCC system while satisfying communication and sensing performance.The considered optimization problem is non-convex and strongly coupled,making it difficult to solve directly.For this reason,an algorithm is proposed based on alternating optimization,closed-form fractional programming,semi-definite relaxation and successive convex approximation to solve the problem.Simulation results show that the algorithm can greatly improve the system performance.关键词
