摘　　要：针对地铁机电施工过程中地铁站内的施工人员以及管理人员无法进行通信这一问题,提出使用基于干扰抵消技术的无线直放站来部署地铁民用通信系统的解决方案,从而实现了地铁站内的2G网络信号的覆盖。阐述了该方案的理论基础、组网架构、测试方案以及试验结果,并证明该方案的可行性。Workers and managers at metro station cannot interconnect during the electromechanical construction. In view of the problem,a solution is proposed,which uses wireless repeater based on interference cancellation technology to deploy the metro civil communication system,and has successfully achieved the goal of metro station 2 G network signal coverage during the electromechanical construction. The theoretical basis,network structure,test scheme and experimental results of the scheme are expounded,the feasibility of the scheme is also verified.
