Abstract

In satellite DS/CDMA communication systems, power control (PC) is critical, and only open loop power control (OLPC) is feasible due to the large propagation delay. We propose an adaptive OLPC method for DS/CDMA satellite communication systems based on a Markov chain channel model. Then, under the assumption that multiuser interference cancellation (IC) is employed, we derive the Erlang capacity of the satellite DS/CDMA system with the OLPC scheme. It is shown that IC and power control error (PCE) affects the Erlang capacity significantly. In addition, dual-satellite diversity is considered and we show that diversity can improve the Erlang capacity of such a system greatly
