摘要

提出了一种基于固定到固定(f2f)符号投影恒定成分分布匹配(SP-CCDM)方法的概率整形调制(PSM)格式。由于SP-CCDM的优化冗余率比传统的CCDM方法小，因此所提出的PSM编码方法是一种杰出的编码方法。代表性信噪比下星座图的变化使频谱效率研究中对损坏信号的根源合理化。f2fsp - ccdm方法为接收信号的净化提供了一种有效的方法。

Dynamic probabilistic shaping modulation based on fixed-to-fixed symbols projection constant composition distribution matching

A probabilistic shaping modulation (PSM) format based on fixed-to-fixed (f2f) symbols projection constant composition distribution matching (SP-CCDM) method is proposed. The proposed PSM is an eminent coding method since the optimized redundancy rate by SP-CCDM is smaller than the one with conventional CCDM method. The change of constellation diagram under representative signal noise ratio rationalizes the root to corrupted signals during the investigation of spectral efficiency. The f2f SP-CCDM method offers an effective way to purification of received signals.
