“…15 Among alternative modulation schemes, APSK has been an emerging one that stands out from other options because of its excellent spectral efficiency and strength and its reputation for dependability in non-linear satellite channels. 16 When paired with improved channel codes like low-density parity checks, APSK can perform well and outperform phase-shift keying (PSK) or standard QAM in data throughput and error performance. 17 This paper proposes a modulator structure consisting of three MRMs to generate an optical 8APSK signal.…”

In this work, an optical 8-amplitude phase shift keying (8APSK) modulator has been designed and successfully simulated using three silicon microring modulators (MRMs). The first two MRMs jointly generate a QPSK signal, while the third MRM is connected in an add-drop configuration to synthesize the final 8APSK signal. The MRMs have a junction volume of 4.5 × 10 −12 cm −3 with carrier recombination lifetime of 100 × 10 −12 seconds. We have obtained the simulated constellation plots at various signal-to-noise ratios and achieved a bit error rate of 10 −3 at around 10.7 dB optical signal to noise ratio.

“…With the increasing demand of satellite services such as mobile services, digital TV broadcasting, data distribution and so on, it is required to adopt the power-and spectrally-efficient high-order modulation schemes like amplitude phase shift keying modulation (APSK) in digital video broadcasting (DVB-S2) [1]. These modulation techniques are with large fluctuation in envelopes and vulnerable to nonlinearity in instinct.…”

The pre-distortion techniques based on traditional direct learning architecture (DLA) are commonly used to linearize high power amplifiers (HPAs) settled in ground-station or on board satellite merely, which cannot achieve a satisfying linearization. In this paper, an improved DLA, considering the satellite channel features with two HPAs in the loop, is put forward. Nonlinear polynomial with 7 order and 4 memory depth is utilized as pre-distorter and recursive least square (RLS) algorithm is adopted for its parameters updating. Simulation results show that with pre-distortion the power spectrum density (PSD) of 16APSK signal achieves about 7.2dB improvement, the EVM of signal constellation is greatly improved up to 61.83%, and desirable system linearization performance is acquired.
