Abstract
This paper investigates the performance of VoIP service in 3G-LTE system and IEEE 802.16m system both in TDD mode, and compares their different system characteristics in details. Thereafter semi-persistent scheduling, dynamic scheduling and link adaptation schemes involved are presented. Finally, this paper demonstrates different VoIP capacities of 3G-LTE and 802.16m under different circumstances, and explains how the different characteristics of the two systems affect the results.
