“…Various channel models have been introduced in the literature to analyze the performance of relaying systems in 5G scenarios. These generalized fading models can be categorized into small-scale multipath scattering propagation models such as Rayleigh [5], Rican [6], Nakagami-m [7], Weibull [8], Nakagami-q [9], η − λ − µ [10], α − λ − µ [11], κ − µ [12], α − µ, and η − µ fading; composite multipath shadowing line of sight (LOS) propagation (composite small-and large-scale fading) models such as generalized Gamma [13] and generalized K [14] fading; and composite multipath scattering and shadowing propagation models with LOS, such as the fluctuating two-ray (FTR) fading model [15,16].…”

This paper presents a generalized approach to the performance analysis of relay-aided communication systems for 5G-and-beyond scenarios. A dual-hop decoding and forwarding scheme is considered in the analysis. The relationship between the outage performance and cumulative distribution function (CDF) of the signal-to-noise ratio (SNR) is exploited to derive a universal expression of the outage probability that is valid for all fading scenarios, irrespective of their nature or complexity. Furthermore, an effort is made to parameterize the channel PDF in such a manner that reflects a practical fading scenario that is commonly encountered in current and future wireless communication systems. The analytical results obtained for various cases are validated through Monte-Carlo simulations.

“…Furthermore, it is also known that the space‐time coding (STC) aided MIMO‐OFDM system can fight against interference as well as multipath fading in more efficient way than the single‐input single‐output (SISO) system. The performance of space time block code and space frequency block code based OFDM system (STBC‐OFDM and SFBC‐OFDM) over various fading channel has been investigated in References 5 and 6. Similar to OFDM, GFDM system can also be combined with MIMO using STBC to exploits the benefits of both STC and GFDM.…”

Due to its low out-of-band emission and high spectral efficiency, the generalized frequency division multiplexing (GFDM) has been adopted as one of the most prominent waveform techniques for the 5G networks. To further combat the deep fading, the space time coding (STC) can be integrated with the GFDM system which provide high diversity gain that results into low symbol error rate at the receiver. In this article, a generalized model of space time coded GFDM system (STC-GFDM) has been proposed. More precisely, a comprehensive analytical framework to compute the average symbol error rate (ASER) is introduced, which can be used for any MIMO configuration, code rate, and arbitrary fading channel. The proposed framework has wider applicability over generalized fading channels and having more accurate exact solution along with easy to evaluate approximate solution. Thus, the proposed framework extends the horizon of performance analysis of STC-GFDM system over any fading scenario, that is not covered so far in the literature. In general, the closed from expressions of exact and approximate along with asymptotic ASER are derived for different fading channels using moment generating function (MGF) approach. Particularly, the ASER analysis has been performed analytically using derived expression over Rayleigh, TWDP, Nakagami-q, and Nakagami-m fading channels for 𝜇-ary quadrature amplitude modulation (𝜇-QAM). This analysis confirms that with the increase in transmit and receive antenna and decrease in modulation order, the ASER performance improves for all fading channels. Also, the improvement in ASER is observed as the power of specular components (ie, LOS paths) increases. Furthermore, these analytical results are validated using Monte-Carlo simulation.

“…Similar to KP-JSFIM, the authors of [31] also considered to jointly use spatial-frequency resource units to generate waveforms, however, antenna selection is carried out before index modulation to reduce the number of required radio frequency links. In [32] and [33], the performances of the SFBC-OFDM system are evaluated with channel estimation error and TWDP Fading Channel, respectively. Moreover, the index modulation concept has also been combined with compressed sensing technique in [34] to reduce the complexity of the receiver.…”

In this paper, a novel framework to efficiently design the waveforms toward heterogeneous networks (HetNets) is proposed. The proposed scheme combines the index modulation (IM) concept with multiple-input multiple-output (MIMO) and orthogonal frequency-division multiplexing (OFDM) techniques and jointly considers the resources on both spatial and frequency domains to optimize the transmission signals. Furthermore, a generalized union bound expression is derived first to disclose the potential diversity gain for the spatial-frequency index modulation (SFIM) system and based on the developed bound different impacts of activating spatial and frequency domains resources for transmission are analyzed. Following the theoretical insights, two novel transmit schemes, termed as enhanced SFIM with non-overlap (ESFIM-NO) and enhanced SFIM with overlap (ESFIM-O), toward higher diversity gains are proposed. We show that the proposed methods can significantly improve the diversity of both index and amplitude phase modulation (APM) domains for achieving higher reliability for the entire HetNets. Finally, the simulation results are given to verify the theoretical analysis and system error performance. INDEX TERMS Multi-dimensional index modulation, coding gains, diversity gains.
