Open-loop Power Control in CDMA Mobile Satellite System

摘要

In Mobile satellite, power control is indispensable for combating shadowing and distance fading,For up link, it guarantee the Base Station receive signal from everyone with the same power. Due to the long delay character ofthe satellite system, open-loop power control scheme is more essential. In this paper, we do some research on this subject, and calculate the power control error in the approximate of log-normal distribution, and the rlation of the receive performance to the number of user per cell.
