摘　　要：采用单网共享基站方案解决相邻线路同频干扰问题,研究该方案的业务链路、时延性能和抗干扰能力。经过试验测试,该方案能够满足2条线路各一辆列车同时出现在共享基站覆盖范围内的CBTC业务传输需求。It is proposed that a solution of single-network shared base station be adopted to solve the problem of same-frequency interference of adjacent lines,and the service link,delay performance and anti-jamming capability of the solution are studied.It is validated via test that the solution can meet the needs of CBTC service transmission for each train on two adjacent lines that are entering into the coverage of the shared base station at the same time.
