“…Hence, through recent research, it has been concluded that energy efficiency, spectral efficiency and capacity of a MIMO system can be enhanced using spatial modulation technique [107][108][109]. However, although several types of research have incorporated NOMA with spatial modulation [110][111][112], there is limited research available on the energy efficiency which can be additionally attained by mitigating inter-user interference present in spatial modulation. Further, since the computational complexity of the spatial modulation scheme is lower than other modulation schemes, the energy efficiency is higher than conventional MIMO -NOMA [108,113].…”

“…In spatial modulation, the index of the transmitting or receiving antennas is used to denote extra information. The concept of spatial shift keying (SSK) was born using the spatial modulation concept [111,114]. In SSK, the transmission of information is done using the antenna index instead of using conventional amplitude or phase modulation techniques.…”

Energy efficiency is a major concern in the emerging mobile cellular wireless networks since massive connectivity is to be expected with high energy requirements from the network operators. Non-orthogonal multiple access (NOMA) being the frontier multiple access scheme for 5G, there exists numerous research attempts on enhancing the energy efficiency of NOMA enabled wireless networks while maintaining its outstanding performance metrics such as high throughput, data rates and capacity maximized optimally.The concept of green NOMA is introduced in a generalized manner to identify the energy efficient NOMA schemes. These schemes will result in an optimal scenario in which the energy generated for communication is managed sustainably. Hence, the effect on the environment, economy, living beings, etc is minimized. The recent research developments are classified for a better understanding of areas which are lacking attention and needs further improvement. Also, the performance comparison of energy efficient, NOMA schemes against conventional NOMA is presented. Finally, challenges and emerging research trends, for energy efficient NOMA are discussed.

“…During the 2010s, research interests in multiuser communications have been focused on non-orthogonal multiple-access (NOMA) [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15], with the motivation of supporting ultra-dense deployment, which faces the problem of supporting more users (or devices) than the number of resource units available. For uplink communications, sparse code spread CDMA [16,17], or simply termed as sparse CDMA (SCDMA), has been proposed for meeting these objectives.…”

“…By contrast, generalized SM (GSM) [33] simultaneously activates multiple TAs to convey multiple APM symbols, while space-time shift-keying (STSK) [34] exploits all degrees of freedom in the joint spacetime domain for information delivery. Additionally, owing to the recent research interest in NOMA, the authors in [15] have proposed and investigated a NOMA-based SM scheme. Similarly, by activating one or a subset of receive antennas with the aid of appropriate transmitter preprocessing, a range of preprocessing assisted SM (PSM) schemes have been proposed.…”

In order to support high-user-load multiple-access (MA), we propose a non-orthogonal MA scheme based on a beneficial amalgam of spatial modulation (SM) and sparse codedivision multiple-access (SCDMA), which is termed as the SM-SCDMA. Hence, SM-SCDMA inherits both the merits of SM with single radio-frequency MIMO transceiver implementation and the advantages of SCDMA relying on low-complexity signal detection. In this paper, we evaluate the potential of SM-SCDMA as well as its low-complexity near-optimum signal detection. Given these objectives, we consider both the maximum likelihood detection (MLD) and the message passing algorithm aided detection (MPAD) that is derived based on the maximum aposteriori principles. In order to evaluate the performance of large SM-SCDMA without relying on time-consuming simulations, we propose new approaches for analyzing the performance of SM-SCDMA systems. A range of formulas that are valid in the signal-to-noise ratio (SNR) region of practical interest are derived. Finally, the performance of SM-SCDMA systems is investigated by addressing diverse design concerns. Our studies and performance results show that SM-SCDMA constitutes a promising MA scheme for the future ultra dense systems. Assisted by the MPAD, it is capable of supporting high-user-load MA transmission associated with a normalized user-load factor of two.

“…It is worth noting that, on top of their spectral efficiency and outage performance, the fairness is also an important issue in NOMA systems [19,20], since there is a trade-off between the total throughput and the user fairness. In addition, since index modulation (IM) [21][22][23][24][25][26] technology has the superiorities for the energy efficiency and low complexity, the authors investigated NOMA-based IM to mitigate inter-user interference, while maintaining high spectral efficiency [27,28].…”

In this paper, an enhanced transmission scheme for cooperative relaying networks with non-orthogonal multiple access (ECRN-NOMA) is proposed. In the proposed scheme, two different kinds of transmission schemes are investigated which are the single signal transmission and the enhanced superposition transmission schemes. Particularly, for the single transmission scheme, a successive interference cancellation (SIC) is utilized to decode the received signal, sent by the relay, at the destination. On the other hand, for the enhanced superposition coded signal transmission scheme, a maximum ratio combining (MRC) is utilized at the destination to improve the ergodic sum-rate (SR) of the proposed system. Specifically, two power allocation (PA) strategies are comprehensively discussed to characterize the performance of our proposed scheme. The achievable average SR of the proposed systems are analyzed for independent Rayleigh fading channels, and also their asymptotic expressions are also provided. Qualitative numerical results corroborating our theoretical analysis show that the enhanced superposition coded signal transmission scheme applied to the proposed ECRN-NOMA improves the SR performance significantly in comparison to the others.
