面向通信抗干扰的IRS-NOMA系统上行链路和速率的优化
Uplink and Rate Optimization of Anti-jamming Communication IRS-NOMA System
摘要
Abstract
Intelligent Reflecting Surface(IRS)can effectively adjust the communication channel,which can improve the anti-interference ability in the battlefield environment.For this purpose,Non-orthogonal Multiple Access(NOMA)technology is combined,and Improving Sum Rate of Uplink based on Manifold Optimization(ISMO)scheme is proposed.The combat vehicles in the battle field are regarded as users.These users form a network.The main objective of ISMO scheme is to maximize the sum rate of uplink by jointly designing the IRS phase shifts and the users’transmit power.The sum-rate maximization problem is firstly formulated.Then the non-convexity of the optimization problem is considered,and the alternative optimization technology is introduced to obtain the solution to user transmit power and IRS phase shift.The simulation results show that compared with the similar scheme,the ISMO scheme improves the system and the rate.关键词
