摘要 随着铁路速度的不断提升,高速铁路上的移动通信网络质量越来越差。首先针对高速铁路移动通信中的多普勒频移现象进行了理论分析,理论分析包括以下几个方面:多普勒频偏对BCCH解调的影响、对手机驻留的影响、对小区重选的影响、不同频段不同车速的频偏对比;在上面理论分析的基础上,结合中国移动和中国联通GSM网络的现状,提出了改进性建议。 Along with the improving speed of railway, the Network Quality of mobile telecommunication is getting worse and worse; Aiming at the phenomena, The article analyze the phenomena of Doppler Frequency shift at first, the analysis including: the impact of Doppler to BCCH demodulation, cell reselection, MS camping; at last combined with the network status of China mobile and China Unicom, give some suggestion.
