刘方森, 李寿鹏, 李方村, et al. Research and test on the scheme of high-speed rail TD-LTE networking coverage[J]. 2015, 28(2): 25-29. DOI: 10.13992/j.cnki.tetas.2015.02.008.
Based on the high-speed rail TD-LTE networking coverage
this paper analyses the elements which effect on TD-LTE system. The paper gives the solutions to serve the high-speed rail coverage problems: doppler shift
frequency switch
high penetration loss. The main solution is that frequency offset compensation to overcome the doppler frequency shift
reasonable layout of the site to overcome the high penetration loss
multi cyclic prefi x to overcome frequent switching. Finally
high-speed rail network test based on the 9:3:2 special time slot allocation to improve the download rate.
