Title
Optimal Power Control for Cognitive LEO Constellation With Terrestrial Networks
Abstract
Power control plays a significant role in cognitive networks, which promotes the spectrum sharing between heterogeneous systems. This letter presents the mathematical model for cognitive low earth orbit (LEO) satellite constellation with terrestrial networks, which takes the dynamic characteristics of the LEO satellite into consideration. Two optimal power control schemes are proposed from the long-term and short-term perspectives, which aims to maximize the delay-limited capacity and minimize the outage probability, respectively. Solutions to the optimization problems are analyzed, and numerical results evaluate the performance of the schemes.
