Power loading is an effective way to improve the system capacity of digital channelized satellite communication (SATCOM) systems, especially for the control of nonlinearities effects of onboard high power amplifier (HPA). However, traditional exhaustive searching and previous multilevel optimization (MO) algorithm will consume much computational time, which are not suitable for in-orbit realtime configuration...
For digital channelized frequency division multiple access based satellite communication (SATCOM) systems, it is a challenging but critical issue to improve the transponder power and spectrum efficiency simultaneously under limited and non-linear high-power amplifier conditions. In this paper, different from the traditional link supportability designs aiming at minimizing the total transponder output...
