Abstract

We proposed a novel 7 bit/4D-sym geometrically-shaped four-dimensional (GS-4D) modulation format based on adjacent quadrant constellations multiplexing, which achieved high nonlinearity tolerance while ensuring lower demodulation complexity. Results show that GS-4D outperforms PM-8QAM and 64PRS.

基于邻象限星座复用的非线性容忍度GS-4D 7bit /4D-Sym调制格式

提出了一种基于相邻象限星座复用的7bit /4D-sym几何形状四维(GS-4D)调制格式，在保证较低解调复杂度的同时实现了较高的非线性容忍度。结果表明，GS-4D优于PM-8QAM和64PRS。
