Abstract
The development of high-speed railways (HSR) has rapidly promoted the updating of high-speed railway wireless communication system. In this paper, performance evaluation and system simulation results with an improved proportional fair algorithm are presented. In the proposed algorithm, different QCI (QoS Class Identifier) priorities have been assigned to different services based on their QoS (Quality of Service) requirements, which has been used to optimize users resource allocation. The simulation results proved that the use of mobile relay could improve the communication performance of the train, and also proved that the proposed algorithm could guarantee the priority and reliable transmission of the voice train service.
