论文摘要
本文研究了雷利褪色通道对单输入多出输出（SIMO）系统的非连锁检测。我们将Kullback-Leibler差异作为设计标准，我们制定了一个多符号星座优化问题，事实证明，该问题具有很高的计算复杂性来构建和检测。我们利用配方问题的结构，将其解散为单一星座设计和多层设计。所提出的多层设计在构建和检测中均具有低复杂性。仿真结果表明，我们的多层次设计比传统的基于飞行员的方案和其他现有的低复杂性多层设计具有更好的性能。
This paper investigates non-coherent detection of single-input multiple-output (SIMO) systems over block Rayleigh fading channels. Using the Kullback-Leibler divergence as the design criterion, we formulate a multiple-symbol constellation optimization problem, which turns out to have high computational complexity to construct and detect. We exploit the structure of the formulated problem and decouple it into a unitary constellation design and a multi-level design. The proposed multi-level design has low complexity in both construction and detection. Simulation results show that our multi-level design has better performance than traditional pilot-based schemes and other existing low-complexity multi-level designs.
