[TuB1-4] Optimization of Probabilistically Shaped MQAM for Maximized System Gains
キーワード：Transmission and Propagation, Advanced modulation and demodulation
We identified that the optimum order m for probabilistically shaped QAM systems is m+2 for wide variety of AIRs and distances. These findings are based on limitations in shaping gain, fiber nonlinearity and DSP complexity.
