在这封信中,我们提出了一种新颖的调制概念,称为索引和合成调制(ICM)。在所提出的概念中,我们使用活动/非活动码字元素的索引和整数的组合来编码信息。在这方面,我们首先确定激活的码字元素,然后利用这些元素的能量水平来识别成分。我们描述了一种使用 ICM 与正交频分复用 (OFDM) 的实用方案,并表明 OFDM 与 ICM (OFDM-ICM) 可以提高 OFDM-IM 的频谱效率 (SE) 和误码性能。我们为所提出的技术设计了一种高效的低复杂度检测器。此外,我们分析了 OFDM-ICM 技术的误差和 SE 性能,并表明它在误差和 SE 性能方面能够超越现有的 OFDM 基​​准。
In this letter, we propose a novel modulation concept which we call 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.
