摘　　要：作为一种新型的反射材料,超智能表面将在未来通信网络中扮演重要的角色。将超智能表面应用于多点协作的毫米波通信系统,可极大提升系统性能。为此,提出基于超智能表面的密集毫米波通信模型,并分析了基于最大合并比(maximal-ratio combining,MRC)接收和选择(selection combining,SC)接收两类协作传输策略下系统性能。具体而言,阐述在Nakagami-m衰落模型下基站所接收的信号,推导了系统中断概率和各态历经容量表达式,并通过仿真验证。同时,通过仿真分析了系统参数对通信系统性能的影响。仿真结果表明,基于SC策略的系统性能略优于MRC策略。传输功率以及LIS中的反射元数对系统性能有较大影响。As a new type of reflective material,large intelligence surface(LIS)will play a vital role in future communication networks.By deploying LISs on dense millimeter-wave communication system with multi-point coordination,the performance of the system is greatly enhanced.Therefore,a dense millimeter-wave communication network model based on LIS are proposed,and the performance of the system under two cases of coordination transmission strategies based on maximal-ratio combining(MRC)reception and selection combining(SC)reception is analyzed.Specifically,the received signals at base station under Nakagami-m fading model are expounded.Then,the outage probability of the system and the expression of ergodi and verified by the simulation results.At the same time,the impact of system parameters on the performance of communication system is analyzed by simulation,The simulation results show that the system performance based on SC strategy is superior to MRC strategy,the transmission power and reflection arity in LIS have greater impacts on the system performance.
