Enhanced proportional fair scheduling for cdma2000 1x EV-DO reverse link

cdma2000 Ix EV-DO Rev.A reverse link adopts dynamic transmission rate technique which allows efficient data transmission with variable data rate according to the channel conditions and system load. Because in reverse link (RL), a higher data rate means a stronger interference, the algorithm of allocating data rate to AT (access terminal) is critical to an interference limited wireless system. Currently, proportional fair scheduling is adopted in cdma2000 1x EV-DO Rev. A forward link, which can make a degree of balance between fairness and throughput. However, it doesn´t suit for reverse link. This paper gives an enhanced proportional fair algorithm for reverse link. And simulation results are present to demonstrate the impact of new algorithm
