“…Similar to the derivation of GSM-MBM, by combining QSM and MBM technique, the quadrature channel modulation (QCM) scheme was formed [154], [155], which is capable of improving the performance over both QSM and MBM alone. Here, we only detail the GSM-MBM to demonstrate how to combine SM techniques with MBM.…”

In fifth generation wireless networks, the escalating teletraffic and energy consumption has necessitated the development of green communication techniques in order to further enhance both the system's spectral efficiency and energy efficiency. In the past few years, the novel index modulation (IM) has emerged as a promising technology that is widely employed in wireless communications. In this paper, we present a survey on IM in order to provide the readers with a better understanding of its principles, advantages, and potential applications. We start with a comprehensive literature review, where the concept of IM is introduced, and various existing IM schemes are classified according to their signal domains, including the frequency domain, spatial domain, time domain and channel domain. Then the principles of different IM-aided systems are detailed, where the transceiver design is illustrated, followed by descriptions of typical systems and corresponding performance evaluation. A range of challenges and open issues on IM are discussed before we conclude this survey.

“…For instance, the authors in [12] and [13] have combined space-time block codes (STBC), and uncoded space-time labelling diversity schemes with MBM concept, respectively. In other research studies, both GSM and QSM techniques have been integrated with MBM approach as presented in [14] and [15], respectively. The scheme that proposed in [15] combines QSM system with MBM transmission technique, and termed as quadrature channel modulation (QCM).…”

Multidimensional generalized quadrature index modulation scheme is proposed in this paper for conveying extra digital information with the aid of the space, radio frequency (RF) mirrors, and time indices. Explicitly, this proposed scheme cleverly combines another proposed time-indexed generalized quadrature spatial modulation (TI-GQSM) system with mediabased modulation (MBM) transmission principle using RF mirrors, and it is referred to as TI-GQSM-MBM scheme. This scheme is attractive because of both the high data rate and the significant performance improvements that can be achieved. The system performance of the proposed schemes in terms of the bit error rate (BER) is evaluated and compared to the performance of the conventional schemes. Simulation results showed that a significant improvement is achieved by the TI-GQSM-MBM scheme as compared to that of TI-GQSM, timeindexed media-based modulation (TI-MBM) and the conventional generalized quadrature spatial modulation (GQSM) schemes for the same rate. It is also demonstrated that the proposed schemes are robust to channel estimation errors (CEEs) as compared to multidimensional generalized spatial modulation (GSM) schemes. Therefore, the proposed schemes can be effectively used as an alternative solution for various 5G and beyond wireless networks.

“…However, similar challenges for MIMO as discussed earlier still exist. More recently, MBM has been applied to quadrature spatial modulation in the form of quadrature spatial media-based modulation [16] and quadrature channel modulation [17]. The presented schemes exhibit significant improvement in spectral efficiency, while retaining a relatively good error performance.…”
