摘要

分层调制技术和概率整形技术近年来得到了广泛的研究。但在光通信系统中，两者同时采用会产生冲突。为了避免不兼容问题，提出了一种分层概率整形方案。计算机仿真结果表明，与分层调制相比，该算法有效地降低了非线性效应，提高了误码率性能。

A Hierarchical Probabilistic Shaping Scheme for Optical Fiber System

Hierarchical modulation technology and probabilistic shaping technology have been widely studied in recent years. However, there is conflict when they are adopted simultaneously in optical communication system. A hierarchical probabilistic shaping scheme is proposed to avoid the incompatibility problem. This algorithm effectively reduces the nonlinear effect and improves the bit error rate performance compared with hierarchical modulation according to computer simulations.
