论文摘要
我们考虑了两用户非相关多访问通道（MAC）的关节星座设计问题。基于对非共连接最大似然性（ML）检测误差的分析，我们提出了新的设计标准，以最大程度地减少误差概率。基于这些标准，我们提出了一种简单有效的结构，该结构包括在分区单用户星座中。数值结果表明，我们提出的指标是有意义的，可以用作目标通过数值优化生成星座的目标，该数值优化以相同的传输速率和功率执行比其他方案更好。
We consider the joint constellation design problem for the two-user non-coherent multiple-access channel (MAC). Based on an analysis on the non-coherent maximum-likelihood (ML) detection error, we propose novel design criteria so as to minimize the error probability. Based on these criteria, we propose a simple and efficient construction consisting in partitioning a single-user constellation. Numerical results show that our proposed metrics are meaningful, and can be used as objectives to generate constellations through numerical optimization that perform better than other schemes for the same transmission rate and power.
