Abstract

This paper propose new bit mapping based on amplitude phase shift keying (APSK) modulation with application to satellite broadband communications in the DVB-S2 standard The APSK modulation outperforms classical 16-QAM and 16-PSK over a typical satellite nonlinear channel due to its intrinsic robustness against the High Power Amplifier (HPA) nonlinear characteristics. The proposed bit mapping considers non-linearity of HPA in the APSK modulation and the performance of APSK modulation for the proposed bit mapping has been compared to the conventional bit mapping.
