论文摘要
在本文中,我们提出了一个新颖的调制概念,我们称之为\ emph {index和组成调制(ICM)}。在拟议的概念中,我们使用主动/停用代码字元素的索引以及整数的组成来编码信息。在这方面,我们首先确定激活的代码字元素,然后利用这些元素的能级来识别组成。我们描述了一种用于与正交频分复(OFDM)使用ICM的实用方案(OFDM),并表明使用ICM(OFDM-ICM)OFDM可以提高频谱效率(SE)和OFDM-IM的误差性能。我们为提出的技术设计了有效的低复杂性检测器。此外,我们分析了OFDM-ICM技术的错误和SE性能,并表明它能够在错误和SE性能方面优于现有的OFDM基准。
In this paper, we propose a novel modulation concept which we call \emph{index and composition modulation (ICM)}. In the proposed concept, we use indices of active/deactive codeword elements and compositions of an integer to encode information. In this regard, we first determine the activated codeword elements, then we exploit energy levels of these elements to identify the compositions. We depict a practical scheme for using ICM with orthogonal frequency division multiplexing (OFDM) and show that OFDM with ICM (OFDM-ICM) can enhance the spectral efficiency (SE) and error performance of OFDM-IM. We design an efficient low-complexity detector for the proposed technique. Moreover, we analyze the error and SE performance of the OFDM-ICM technique and show that it is capable of outperforming existing OFDM benchmarks in terms of error and SE performance.
