与DP-BPSK相比具有改进性能的OSNR的三维单工调制格式
A 3-Dimensional Simplex Modulation Format with Improved OSNR Performance Compared to DP-BPSK
摘要：
新的三维调制格式3D-Simplex提供比DP-DPSK高1.2 dB的OSNR容限，同时表现出相同的频谱占用，每个符号调制两个比特。我们通过实验验证了这种好处，并评估了非线性环境中的传输性能。所有的实验结果都得到了仿真的证实。3D-单纯形的优点在高度非线性状态下没有保持，但性能仍然与DP-DPSK相当。
英文摘要：
The novel 3-dimensional modulation format 3D-Simplex offers potentially 1.2 dB higher OSNR tolerance than DP-DPSK while exhibiting the same spectral occupancy, modulating two bits per symbol. We verify this benefit experimen-tally and evaluate the transmission performance in a non-linear environment. All experimental results are confirmed by simulations. The benefit of 3D-Simplex is not maintained in the highly non-linear regime, but the performance is still comparable to that of DP-DPSK.
