“…14. A total of l × p binary bits are partitioned into l × p 1 bits for the index selector and l × p 2 bits fed to the M-ary constellation mapper to generate the l subframes s (i) It can be seen that TD-IM is equivalent to FD-IM, where time slots are analogous to subcarriers. The dual-mode IM technique used in DM-OFDM can also be applied to SC-IM, yielding the dual-mode SC-IM (DM-SCIM) scheme [28], where the l s time slots of each subframe are activated by two distinguishable constellation alphabets. By assuming that k time slots of each subframe are modulated by M A -ary constellation, and the others are modulated by M B -ary constellation, then its data rate can be calculated as…”

“…Additionally, the faster-than-Nyquist (FTN) rate sampling technique is incorporated to SC-IM and DM-SCIM, respectively, in [28] and [29] to enhance the data rate over the standard SC-IM and DM-SCIM, at the cost of higher intersymbol interference (ISI). For instance, unlike the conventional time-orthogonal transmission scheme based on Nyquist criterion, where the minimum symbol interval is T 0 = 1 2 W with W denoting the signal bandwidth, the FTN-IM of [29] shortens the symbol interval as T = αT 0 in which α < 1.…”

“…Fig. 16 compares the BER performance of the conventional SC system with those of the two typical TD-IM schemes, SC-IM and DM-SCIM, under the frequency-selective Rayleigh fading channel at the spectral efficiency of 2.59 bit/s/Hz [28]. To achieve this high spectral efficiency, the SC system adopts 8-PSK.…”

“…Specifically, in each data frame, only a fraction of the signaling time slots are activated for data transmission, and the corresponding indices carry information [26], [27], which leads to significant performance gain over its non-IM-aided counterpart. The multi-mode IM philosophy and the faster-than-Nyquist signalling are also applied to TD-IM [28], [29] to further enhance the system performance. Furthermore, TD-IM can be combined with the space-time block code (STBC) system [30], [31], where only subset of the dispersion matrices are selected for data transmission, while their indices carry extra information bits [32], [33].…”

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.

In this paper, we propose a faster-than-Nyquist (FTN) signaling-aided space-time multi-mode index modulation (IM) scheme with a low-complexity Gaussian message passing (GMP) based receiver. The advantages of spatial domain IM, time-domain IM relying on multiple modes and FTN signaling are explored. Specifically, multi-mode IM is employed in time domain by activating all time slots, hence the spectral efficiency is improved substantially compared to its single-mode counterpart. Meanwhile, the transmission rate is further increased by utilizing FTN signaling. At the receiver, based on the state-space model of IM symbols, a two-layer Forney style factor graph (FG) representation for the system is constructed to exploit the truncated inter-symbol interference structure imposed by FTN. Belief propagation is invoked to update the messages over the FG. The discrete messages from the channel decoder are properly approximated to be Gaussian for reducing the complexity of joint detection of multidimensional index modulated symbols. Moreover, the extrinsic information from the equalizer is derived with a concise representation. A lowcomplexity log-likelihood ratio calculation method is further proposed, where the search space is significantly reduced using a Gaussian mixture model. Simulation results demonstrate that the proposed scheme outperforms the existing schemes in terms of bit error rate given the same spectral efficiency. The outstanding performance and low complexity of the proposed GMP-based receiver are also verified by comparisons with existing methods.
