Abstract

Satellite systems are some of the key telecommunications systems which have the potential of achieving ubiquitous and global personal communications. The satellite component of IMT-2000 based on DS/CDMA system, such as SW-CDMA, has been proposed. For such systems, power control (PC) is critical, and only open loop power control (OLPC) is feasible. In this paper, we propose an adaptive OLPC method for DS/CDMA satellite communication systems based on a Markov chain channel model. We will then derive the Erlang capacity of the satellite DS/CDMA system with this PC scheme and demonstrate that Power Control error (PCE) affects the Erlang capacity significantly. In addition, dual-satellite diversity will be considered and we will show that diversity can significantly improve the Erland capacity of the satellite CDMA system.
