Abstract

In this paper, the results of the quality of service for VoIP service over TD-SCDMA HSDPA system are presented. The performances of the system with different scheduling algorithms and different retransmission times are simulated and analyzed. Dynamic scheduling, adaptive modulation and code (AMC), dynamic HARQ are implemented in the system-level simulation and some recommends for HARQ channel number and retransmission time and optimality are given.
