A 4+12+16 Amplitude Phase Shift Keying (APSK) modulation outperforms other 32-APSK modulations such as rectangular or cross 32-quadrature amplitude modulations (QAMs) which have a high peak to average power ratio that causes non-negligible amplitude modulation to amplitude modulation (AM/AM) and amplitude modulation to phase modulation (AM/PM) distortions when the signal is amplified by a high-power amplifier (HPA). Thus, this modulation scheme has been recommended as modulation scheme in the Digital Video Broadcasting-Satellite2 (DVB-S2) standard. In this paper, we present a new bits-to-symbol mapping to improve a bit error rate (BER) for a 4+12+16 APSK signal in a nonlinear satellite channel and analyze the BER.
