Geometrically Shaped Constellations (2D) for a Low Complexity Partially-Coherent AWGN Demapper

2D geometrically shaped constellations that are simultaneously robust to both residual phase noise (RPN) and AWGN (named as LCM-RPN, where LC is the low-complexity receiver metric from [1]) for 8 to 64-ary PCAWGN reception using a mismatched PCAWGN model. We added AWGN-only shaped constellations (LCM-AWGN) to serve as a reference; the term M is the modulation cardinality.Note: This is a supplementary dataset for journal submission. The uploaded constellations are optimised for a low-complexity PCAWGN demapper from [1], although they may also work well with the exact channel model and other PCAWGN approximations. Each of the constellations comes with linewidth symbol time product, SNR (i.e. signal to noise ratio) and RPN variance. [1] M. Sales-Llopis and S. J.

本数据集包含二维几何形状的星座图，该星座图对残留相噪（RPN）和加性高斯白噪声（AWGN，简称LCM-RPN，其中LC代表来自文献[1]的低复杂度接收指标）具有同时的鲁棒性，适用于8至64-ary PCAWGN接收，并采用不匹配的PCAWGN模型。为提供参照，我们添加了仅包含AWGN的形状星座图（LCM-AWGN）；术语M表示调制阶数。注：本数据集为期刊投稿的补充数据集。所上传的星座图针对文献[1]中的低复杂度PCAWGN解调器进行了优化，尽管它们也可能与精确信道模型和其他PCAWGN近似效果良好。每个星座图均附带线宽符号时间乘积、信噪比（即信噪比）和RPN方差。[1] M.
