Abstract

Due to the rapid development of high-speed railways all over the world, Railway digital mobile communication system is one of the most important parts which bears various services. However, it has been a challenge to support high speed (e.g., above 350 km/h) mobile user with broadband communication in a challenging environment including rapidly fading radio channels, Doppler frequency shift and fast handover problem. An Improved Distribution Antennas System for High-Speed Railway is proposed in this paper to solve the problem of fast handover in the traditional cellular network. The overlap region of two adjacent Logical Cells is composed by a complete cell, which is named Fixed Handover Cell. Therefore, there is sufficient time to complete the handover. It can effectively avoid the occurrence of a ping-pong effect. Its advantages include seamless handover, simple handover, and cost-effective deployment to support high mobility.
