Performances of 2r16APSK and DVB-S2 16APSK Modulations over a Two-Link Satellite Channel

In this paper, the 2r16APSK modulation is contrasted with 16APSK adopted in digital video broadcast standard, DVB-S2, aiming at verifying if the can be considered an alternative choice for the DVB-S2 and other alike communication systems when subjected to nonlinear distortions. To end, performances of both modulations are assessed terms metrics: bit error rate (BER), constellation figure merit (CFM), peak-to-average power ratio (PAPR), total degradation (TD) versus input back-off (IBO), spectral regrowth, transmitted signal goes through a two-link satellite channel under memoryless nonlinear distortion produced by traveling wave tube amplifier (TWTA), which described Saleh model. The results show that the 2r16APSK indeed choice.
