“…where the matrix I g explained in (8) illustrates the specific index combination of selecting K active indices out of N a available indices in the virtual domain for M transmit antennas. Additionally, according to the principle of the OMP algorithm, the process ofÂ g =ÂI g creates an over-determined scenario for the proposed detection system [43].…”

Abstract-In space-time shift keying (STSK), the information is conveyed by both the spatial and time dimensions, which can be used to strike a trade-off between the diversity and multiplexing gains. On the other hand, orthogonal frequency division multiplexing (OFDM) relying on index modulation (IM) conveys information not only by the conventional signal constellations as in classical OFDM, but also by the indices of the subcarriers. In this paper, we combine the benefits of STSK and IM in order to strike a flexible trade-off between the throughput and bit-error performance by transmitting extra information bits in each subcarrier block, whilst increasing the diversity order. In order to further improve this trade-off, as well as to decrease the complexity of the detector, compressed sensing (CS) is combined with the proposed STSK-aided IM system. We first present the Maximum LikeLihood (ML) detection, which forms the best-case bound on the proposed system's performance. Then we propose a pair of reduced-complexity detection algorithms capable of approaching the ML detector's performance. Furthermore, in order to attain a near capacityperformance, we propose a soft-input soft-output (SISO) decoder that is capable of exchanging soft-information with a channel decoder through iterative decoding.

“…Shown in Figure 26 multiple modulation techniques used for mmWaves. Indeed, using OFDM at mmWave frequencies has numerous advantages, hence it is already deployed in IEEE802.15.3c [14] for WPAN and also considered for other systems, as detailed in [30], [43], [81], [231]- [233]. However, OFDM suffers from high PAPR and it is sensitive to phase noise, hence leading to less efficient linear class-A power amplifiers, which thereby degrade the overall performance of the system.…”

“…• Multi-User Grouping: Many contributions have lately considered user grouping in Multi-User (MU) systems [177], [231], [232], [239], [240], which is particularly beneficial at mmWaves due to their high attenuation that restricts the coverage area and to counteract the sparse multipath scattering. In this case, some of the users receiving a cluster from the same reflecting objects would share the same second-order spatial characteristics and hence maybe considered as one group [178].…”

“…For instance, beamforming relying on directional antenna configurations is a key enabling technique for mmWave systems employing any MIMO technique for the sake of achieving performance enhancements. This facilitates the concept of multifunctional antenna arrays (MFAA), which are capable of simultaneously achieving different MIMO gains, such as diversity, multiplexing and beamforming gains [231]- [233], [241]- [245].…”

Abstract-The millimeter wave (mmWave) frequency band spanning from 30 GHz to 300 GHz constitutes a substantial portion of the unused frequency spectrum, which is an important resource for future wireless communication systems in order to fulfill the escalating capacity demand. Given the improvements in integrated components and enhanced power efficiency at high frequencies, wireless systems can operate in the mmWave frequency band. In this paper, we present a survey of the mmWave propagation characteristics, channel modeling and design guidelines, such as system and antenna design considerations for mmWave, including the link budget of the network, which are essential for mmWave communication systems. We commence by introducing the main channel propagation characteristics of mmWaves followed by channel modeling and design guidelines. Then, we report on the main measurement and modeling campaigns conducted in order to understand the mmWave band's properties and present the associated channel models. We survey the different channel models focusing on the channel models available for the 28 GHz, 38 GHz, 60 GHz and 73 GHz frequency bands. Finally, we present the mmWave channel model and its challenges in the context of mmWave communication systems design.

“…As a continuous work, in [144], OFDM was amalgamated with differential STSK, and the iterative soft multiple-symbol differential sphere decoder was employed to obtain the SNR gain over the conventional soft-decision-aided differential detection method. More recently, Hemadeh et al [145] generalized the concept of STSK to the multi-user MIMO scenario, Fig. 16.…”

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.
