| Abstract(in English) | Many researches have been dedicated to the TCP performance analysis over wireless link, where a fixed PER has been often assumed. However, the PER is temporally and geographically changeable by fading, shadowing and near/far effect, inter-cell interference and the effect of power control. In this paper, we analyze the impact of a power control on the PER in a CDMA downlink by computer simulation. Our simulation results show that there is an optimal step size of power control for a given error-collecting code. This paper also discusses a state transition realization of the measured PER with a simple model. Furthermore, we also analyzes the throughput of TCP, then this paper clarifies the difference of throughput between the fixed PER, the modeling PER and the simulation results. Finally, the result of throughput shows that ARQ is a very effective technique in the wireless network system. |
