Abstract:
This paper studies the implementation and performance of the Proportional-Fair(PF) scheduling algorithm, which is affected by the technologies such as Packet-Division Multiple Access(PDMA). Simulation results show that by introducing PDMA and HARQ in 1xEV-DO Rev A, PF scheduling algorithm can obtain a satisfied forward throughput and efficiently meet the delay request of real-time traffics.
