Adaptive pf scheduling algorithm in LTE cellular system

The traditional proportional fair scheduling algorithm can only provide users with limited fairness while the channel is changing. To solve this problem and enhance the fairness between users, an adaptive proportional fair scheduling algorithm for LTE (Long term Evolution) system is proposed. It adjusts the scheduling priority according to individual user´s channel condition. The proposed algorithm provides a good trade-off between capacity and fairness, and the simulation results show the validity.
