- This paper presents an efficient closed-loop power control algorithms for the next generation mobile satellite systems. Although we could not see any active role of a satellite system in the 3G networks, satellite system will provide strong advantages in future systems for certain applications. Because a satellite link has longer round trip delay than a terrestrial link, we need time delay compensation- and efficient channel estimation algorithms that would make the satellite component especially efficient. After presenting the satellite radio interface of the 3G system, we suggest powerful power control which need to be considered in the beyond 3G systems. © 2006 IEEE.
