摘要:

本文研究了两用户非相干多址信道(MAC)下的联合星座设计问题。基于对非相干最大似然(ML)检测误差的分析,我们提出了新的设计准则,使错误概率最小化。基于这些标准,我们提出了一个简单而有效的建设,包括在划分一个单用户星座。数值结果表明,我们提出的指标是有意义的,并可以作为目标,通过数值优化,性能优于其他计划相同的传输速率和功率生成星座。

英文摘要:

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.
