Abstract: The traditional proportional fairness wireless network resource scheduling strategy could not effectively guarantee the fairness of users, and had the shortcomings of low resource utilization of wireless network communication system, so we designed a resource scheduling optimization strategy based on spectrum coefficient and proportional fairness algorithm for wireless network communication system to solve the problems existing in the current resource optimization scheduling process of wireless network communication system. Firstly, the channel model of wireless network communication system was established, and the reasonable spectrum coefficient was determined by adaptive genetic algorithm. Secondly, according to proportional fairness algorithm, the scheduling priority was calculated, and the resources of wireless network communication system were allocated to users, and the shortcomings of traditional proportional fairness algorithm were improved accordingly. Finally, the performance of wireless network communication system was analyzed on the platform of MATLAB 2016. The resu
lts show that the proposed strategy can better ensure the fairness of users’ use of resources, improve throughput of wireless network communication system, and improve the resource utilization of wireless network communication system.
