Abstract
Over the past decades, earth orbiting Satellites may employ different linearization techniques to cope with the increasing demand of spectral efficiency and data quality. Unlike the free-space transmission on earth, satellite links typically suffer from low signal to noise ratio and atmospheric impairments. This paper provides a framework to investigate the effect of radiowave propagation characteristics on non-linear power amplifiers. In particular, Nakagami-m fading is applied to the real-time amplifier response collected from a radio frequency testbed. The experimental results show that the prediction model in the context of digital pre-distortion correction could be optimized in order to index the atmospheric fade level and to compensate for the nonlinearities arising from the earth-space impairments.
