Abstract

The probabilistic amplitude shaping(PAS) scheme based on amplitude shift keying(ASK) has attracted much attention as a signal-shaping solution. However, due to the limitation of nonlinear effects in practical applications, the robustness of the ASK modulation scheme is far worse than amplitude and phase shift keying(APSK) modulation. Therefore, we design a distributed mapping scheme based on APSK and propose the corresponding PAS scheme. To find the balance between the rate loss and the shaping gain brought by the shaping scheme, this paper utilizes Monte Carlo to simulate and successfully verify that the proposed scheme performs well at different transmission rates, with a maximum of 0.67 dB.
