论文摘要
在本文中，我们提出了一个新的结构化硕士星座，用于通过单输入多数输出（SIMO）瑞利（Rayleigh）阻滞通道，以实施非相关通信。我们称之为草的星座是基于保存从单位HyperCube到线条司法的映射的措施。星座结构允许符号生成，低复杂性解码以及简单的位至符号灰色编码。仿真结果表明，草晶格的符号和位错误率性能接近数值优化的非结构化星座，并且比文献中提出的其他结构化星座更有效，并且基于先导的方案。
In this paper, we propose a new structured Grassmannian constellation for noncoherent communications over single-input multiple-output (SIMO) Rayleigh block-fading channels. The constellation, which we call Grass-Lattice, is based on a measure preserving mapping from the unit hypercube to the Grassmannian of lines. The constellation structure allows for on-the-fly symbol generation, low-complexity decoding, and simple bit-to-symbol Gray coding. Simulation results show that Grass-Lattice has symbol and bit error rate performance close to that of a numerically optimized unstructured constellation, and is more power efficient than other structured constellations proposed in the literature and a coherent pilot-based scheme.
