我们研究了大多数相干传输系统使用的四维信号空间中的节能调制格式。讨论了在有前向误差校正和没有前向误差校正的情况下灵敏度和光谱效率的权衡。
We investigate power-efficient modulation formats in the four-dimensional signal space that is used by most coherent transmission systems. The sensitivity and spectral efficiency trade-off is discussed, with and without forward error correction.
