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
