This paper investigates the handover performance on high speed train (HST)via different speed under three scenarios, which are viaduct environment,cutting environment and urban area. To provide stable wireless service, weadopt Long Term Evolution (LTE) for high speed railway (HST) system. Moreover,we consider the effect of speed on handover procedure. Interchannelinterference (ICI) caused by the Doppler frequency spread is related to thespeed of HST, which is considered into the proposed system to evaluate thesystem handover performance including handover starting time and handoverdelay. Numerical results show the parameters in the system including SNR,throughput, handover starting time and handover delay. The proposed systemprovides some insights for practical railway system.
