Abstract
WiMAX system is based on OFDMA, and it is very suitable for VoIP traffic. At the same time, frame bundling is an technique to improve the performance of VoIP, and so it is applied to WiMAX system in this paper. The simulation results indicate that when the system is inadequate of bandwidth, this technique indeed reduces the PER and delay jitter of the VoIP users, and enhances the spectrum efficiency.
