论文摘要
直观的球体包装参数用于获得可分析的封闭形式近似值，以实现编码调制传输系统可实现的信息速率，仅文献中只能进行分析上的表达式。这些近似值提供了许多见解，具有有用的属性，并促进了此类系统的设计/优化。它们适用于各种红衣主教的星座（包括大型），在整个信噪比范围内既简单又相当准确，并且与最近最新实验的实验率相比有利。
The intuitive sphere-packing argument is used to obtain analytically-tractable closed-form approximations for achievable information rates of coded modulation transmission systems, for which only analytically-intractable expressions are available in the literature. These approximations provide a number of insights, possess useful properties and facilitate design/optimization of such systems. They apply to constellations of various cardinalities (including large ones), are simple yet reasonably accurate over the whole signal-to-noise ratio range, and compare favorably to the achieved rates of recent state-of-the art experiments.
