Summary Cooperative communication is a significant technology for fifth generation (5G) and beyond wireless communication to improve the quality of service (QoS) in massive networks. In addition, it serves as a promising candidate along with non‐orthogonal multiple access (NOMA) scheme to increase the spectral efficiency. Conventionally, cooperative‐NOMA (C‐NOMA) systems are analysed by assuming perfect successive interference cancellation (SIC) and imperfect SIC (I‐SIC) over Rayleigh, Rican, α−μ, Hoyt fading channels, and so on. In this paper, near–far relay (NFR) C‐NOMA system is analysed aiding perfect SIC, perfect channel state information (CSI), imperfect (I‐CSI) and (I‐SIC) over Rayleigh fading channel. Initially, we derive analytical expressions of outage probability (OP) by considering I‐SIC and I‐CSI for NFR‐C‐NOMA system. The accuracy of analytical results is verified through Monte Carlo (MC) simulations. Interpretation of the results conveys that I‐CSI and I‐SIC have a substantial impact on OP in NFR‐C‐NOMA scheme and existing schemes. Later, we examined impact on OP in NFR‐C‐NOMA by varying relay position, target rate of users and jointly considering the I‐SIC, I‐CSI. Further, it is also observed that the NFR‐C‐NOMA scheme shows better outage performance than state‐of‐the‐art schemes.

“…Combining the advantages of MIMO transmission techniques, especially (G)SM and its special cases, with the cooperative communication has been studied in the literature 21–38 . An exact error rate expression, closed form symbol error rate, outage probability and normalized capacity expressions are derived for classical AF networks using orthogonal STBC (OSTBC) 21 . BERs are obtained for non‐adaptive DF and adaptive DF networks when the transmission is realized with OSTBC over Rayleigh fading channels 22 .…”

Distributed space‐time block coding based cooperative generalized spatial modulation

Summary In this study, two novel distributed space‐time block coding based cooperative generalized spatial modulation networks are proposed, and their theoretical analyses are derived. The first network is a three‐node cooperative system, consisting of a source (S), a relay (R), and a destination (D). In this design, S sends a GSM symbol to R and D in the broadcast phase. In the relay phase, if R decodes the received signal correctly, it encodes the orthogonal counterpart of the GSM symbol, and sends it to D. If R has a decoding error, it sends a failure to S, and S realizes the R's transmission. The second network is designed with two relays. Here, S sends the GSM symbol to R1, R2, and D in the broadcast phase. In the relay phase, if both relays decode the incoming signal correctly, R1 regenerates the GSM symbol coming from S, and R2 encodes the orthogonal version of it. After encoding, both send them to D in a successive manner. If any or both relays fail, S sends the symbol of R2 in the relay phase. Theoretical and asymptotic analyses as well as simulation results are provided for both networks. It is seen that derived analytical expressions match with the simulation curves. Moreover, since we use the GSM in the proposed methods, their data rates are higher for the same number of transmit antennas. Even for the same spectral efficiency, they provide a significant diversity gain and a better error performance than the existing methods.

“…The dual-hop (DH) and multiple hop (MH) schemes, which usually serve to achieve diversity gain (DG), are two main classes of relaying protocols. Besides, the literature also suggested two major relay protocols such as amplify and forward (AF) [8][9][10] and decode and forward (DF) [11,12].…”

“…To characterize the performance of AF-PDMA, we derived system throughput data and OP and performed diversity order (DO) analysis. In [9], the authors consider the orthogonal space-time block code (OSTBC)-based AF cooperative communication system and derive the moment-generating function (MGF) over Rayleigh fading links. In [10], the authors examined the relay selection-based, full-duplex AF relaying protocol considering a scenario in which the primary users (PUs) have access to spectrum and many pairs of secondary users (SUs) have no dedicated spectrum.…”

In this paper, we consider the selective decode and forward cooperative communication system and investigate its performance over time-selective fading in the presence of nodes' mobility and channel estimation errors. Closed-form expressions for the outage probability (OP) and per-block average pairwise error probability (PEP) are derived, considering constraints at the relay, source, and destination nodes. We assume that both dual and multiple hops are subject to independent but non-identically distributed time-selective Nakagami-m fading channel. It has been observed that with an increase in the value of shape parameter and link strength of the relay-to-destination (RD) fading link gain, the per-block average PEP performance improves. Also increasing RD link gain is more significant than increasing the shape parameter of the RD link. The OP performance for optimal power allocation factors is better than its performance for equal power allocation factors. It is demonstrated that the OP decreases with increasing the value of distance-dependent power transfer factors (PTFs). Further, it has been observed that due to the mobility of nodes and imperfect channel state information, the PEP performance of the system experiences degradation, especially for high values of signal-to-noise ratio. Furthermore, when all the nodes are static and the estimation processes are perfect, the asymptotic error floors vanish, i.e., the nodes' mobility impact is removed. Monte Carlo simulation results confirm the accuracy of the analytical results.
