在实验中将来自 D4 点阵 (256-D4) 的 256 个点的四维调制格式与 PM-16QAM 进行了比较。 256-D4 在高 OSNR 下更敏感,但具有 21.3% 的开销 Turbo 乘积码,PM-16QAM 的性能优于 256-D4。
A four-dimensional modulation format with 256 point from the D4-lattice (256-D4) is compared to PM-16QAM in experiments. 256-D4 is more sensitive at high OSNR but with a 21.3% overhead turbo product code, PM-16QAM outperforms 256-D4.
