Summary:The rapid development of high-speed railway technology causes the contradiction between the users' service requirements and the wireless resources continue to grow. Aiming at the high-speed railway communication environment, with the goal of ensuring users' satisfaction and improving system throughput, the single delay factor is extended to the maximum data packet delay, packet loss rate and minimum rate requirements to construct quality of service (QoS) index affected by multiple factors. Combining the improved proportional fair scheduling algorithm with traditional Water-Filling algorithm, a proportional fair power allocation optimization algorithm is proposed. The simulation is verified in terms of optimization algorithm and traditional algorithm comparison, service priority scheduling factor and satisfaction factor of users, the results show that the optimization algorithm has higher user satisfaction and improved system throughput.
