论文摘要
在本文中，我们提出了一种具有索引调制（OFDM-IM）方案的新型正交频施加多路复用，我们称之为Q- ARY多模式OFDM-IM（Q-MM-OFDM-IM）。在拟议的方案中，Q分离M-ARY星座在每个子载波上重复使用，并将最大距离分离的代码应用于这些星座的索引以实现最高数量的索引符号。对于拟议的方案，可以证明低复杂性子载波检测可能。进一步分析了频谱效率（SE）和提议方案的错误率性能。结果表明，所提出的方案表现出非常灵活的结构，能够将常规OFDM作为特殊情况。还表明，在保留低复杂性结构的同时，就误差和SE性能而言，所提出的方案能够大大优于其他OFDM-IM方案和常规OFDM。
In this paper, we propose a novel orthogonal frequency division multiplexing with index modulation (OFDM-IM) scheme, which we call Q-ary multi-mode OFDM-IM (Q-MM-OFDM-IM). In the proposed scheme, Q disjoint M-ary constellations are used repeatedly on each subcarrier, and a maximum-distance separable code is applied to the indices of these constellations to achieve the highest number of index symbols. A low-complexity subcarrier-wise detection is shown possible for the proposed scheme. Spectral efficiency (SE) and the error rate performance of the proposed scheme are further analyzed. It is shown that the proposed scheme exhibits a very flexible structure that is capable of encompassing conventional OFDM as a special case. It is also shown that the proposed scheme is capable of considerably outperforming the other OFDM-IM schemes and conventional OFDM in terms of error and SE performance while preserving a low-complexity structure.
