A new generic multistep power control algorithm for the LEO satellite channel with high dynamics

LEO satellite CDMA systems, characterized by round-trip delay and high vari ation in slow fading, call for different considerations on power control al gorithms. Based on the criteria of fast response, small over-compensation, oscillation-avoiding and minimum power control error, the transient behavio rs of the fixed step, adaptive step, and multistep power control algorithms are investigated and compared. A new generic multistep power control algor ithm with excellent dynamic performance is proposed for LEO satellite syste ms.
