论文摘要
由于代码字元素之间的依赖性，索引调制（IM）和相关调制技术难以为实际问题提供简单的解决方案，例如信息位和星座点之间的灰色编码；通道编码的信息位的低复杂性对数可能比率（LLR）计算。在本文中，我们表明，基于简单的最大距离可分离（MDS）代码的调制技术，换句话说，MDS调制可以为这些问题提供简单而有效的解决方案，从而使MDS技术在编码的存在下更有益。我们还将MDS方法的编码错误性能与IM方法进行了比较，并证明MDS调制优于IM。
Due to dependence between codeword elements, index modulation (IM) and related modulation techniques struggle to provide simple solutions for practical problems such as Gray coding between information bits and constellation points; and low-complexity log-likelihood ratio (LLR) calculations for channel-encoded information bits. In this paper, we show that a modulation technique based on a simple maximum distance separable (MDS) code, in other words, MDS modulation, can provide simple yet effective solutions to these problems, rendering the MDS techniques more beneficial in the presence of coding. We also compare the coded error performance of the MDS methods with that of the IM methods and demonstrate that MDS modulation outperforms IM.
