Abstract

WiMAX system is based on OFDMA, and it is very suitable for VoIP traffic. At the same time, aggressive AMC and frame bundling are two important techniques to improve the performance of VoIP, and so they are applied to WiMAX system in this paper. The simulation results show that when the system is in short of bandwidth, these two techniques indeed reduce the PER and delay jitter of the VoIP users, and also enhance the spectrum efficiency.
