An open-loop power control method for mobile satellite system

In this paper, we propose an architecture of open-loop power control, which is applicable to Ku/Ka-band mobile satellite systems. When a mobile terminal tries to access a HUB system initially, the location of the mobile terminal is not fixed. If the transmission power of the mobile terminal is in a low state, the probability of initial access failure may be increased. For this, we propose an open-loop power control method which can be applied to mobile terminals which are located in any beam coverage. In the mobile environment, a communication channel can be changed dynamically, and our architecture can work in a dynamic environment.
