The capacity of a multiple-input–multiple-output (MIMO) channel with N transmit and receive antennas for highspeed railways (HSRs) is analyzed based on the 3-D modeling of the line of sight (LOS). The MIMO system utilizes a uniform linear antenna array. Instead of increasing the number of antennas or simply changing the parameters of the antenna array, such(More)
With the development of high-speed railway and public growing demand on data traffic, people pay much more attention to provide high data rate and high reliable services under high mobility circumstance. Due to the higher data rate and lower system latency, long-term evolution (LTE) has been chosen as the next generation’s evolution of railway mobile(More)
With the expansion of the railway industry and the upgrade of railway speed, the reliability and efficiency of wireless communication systems in high speed railway attract the public attention. The high speed brings about more severe Doppler Effect, the postponement of handover triggering location and more frequent handover. Therefore the influence caused(More)
With the development of high-speed railway all over the world, the reliability and communication of bullet train depends on the wireless communication between train and Base Stations (BSs) along the railroad. Traditional handover scheme of Long Term Evolution (LTE) network is that ‘neighboring cell becomes better than an offset relative to the(More)
Voice over IP (VoIP) in LTE-R (LTE for Railway) will replace the circuit-switched (CS) voice service of the GSMR (GSM for Railway). However, it will face new problems in high speed railway scenario. In overlapping areas, the handover signaling (i.e. handover measurement and decision) is of higher priority than Hybrid Automatic Repeat reQuest (HARQ)(More)
