To improve the throughput of orthogonal frequency division multiple access downlink resource allocation system and meet user requirements of multi-traffic,aquality of service based resource allocation algorithm is proposed on the basis of proportional fairness algorithm.Based on the proportional fair algorithm and according to the user waiting delay in the queue,the user requirements of multi-traffic and channel conditions,this algorithm is used to designe the fairness factor and multi-traffic factor and then to calculate the user priority for dynamically allocating resource.The simulation results indicate that the throughput and fairness of the system are improved compared with traditional algorithm.
