沪昆高铁GSM-R直放站多径干扰优化简析
|
摘要
GSM-R网络的多直放站区间场景下的时延多径,会造成CTCS-3降级而影响列车运行秩序。此类问题难以查找,处理周期较长,是GSM-R网络优化的难点。结合实例对沪昆高铁ZJYW10到ZJ-YW11区段直放站造成的时延多径问题进行分析,并提出有效解决方案,改善GSM-R网络指标。
In the Multi-repeater scenario of GSM-R Network, time delay multipath will degrade CTCS-3 and affect train operation order. This kind of problem is difficult to find and has a long processing cycle, which is the difficulty of GSM-R network optimization. In this paper, the delay multipath problem caused by repeater in a section of Shanghai-Kunming high-speed railway is analyzed and an effective solution is proposed, which improves the performance of GSM-R network.
