“…Based on (11) all degree-of-freedoms in terms of AS (i.e., BS transmit antenna, and relay's receive and transmit antenna) are used to maximize the e2e at U2, hence there is no degree-of-freedom available to maximize the e2e SINR at U1. Therefore, under similar conditions the received SINR at the near user in max-U1 AS scheme outperforms the received SINR at the near user in max-U2 AS scheme.…”

“…Now we turn our attention to derive P S2 out,2 . According to (11) the e2e SINR at U2 is maximized when each term inside in the minimum function is maximized. Therefore, a transmit antenna at R is selected such that γ k RU2 is maximized, i.e., γ k RU2 is the largest of M T exponential RVs with parameter γRU2 .…”

“…However, in the relay-assisted cooperative NOMA, the far user is being helped by a dedicated relay [7]. However, halfduplex (HD) relaying in such networks incurs spectral efficiency losses [8]- [11]. Thus, one may recover this spectral loss by exploiting full-duplex (FD) relaying, where the relay node can receive and transmit simultaneously in the same frequency band.…”

In this paper, we address the antenna selection (AS) problem in full-duplex (FD) cooperative non-orthogonal multiple access (NOMA) systems, where a multi-antenna FD relay bridges the connection between the multiantenna base station and NOMA far user. Specifically, two AS schemes, namely max-U1 and max-U2, are proposed to maximize the end-to-end signal-to-interference-plus-noise ratio at either or both near and far users, respectively. Moreover, a two-stage AS scheme, namely quality-of-service (QoS) provisioning scheme, is designed to realize a specific rate at the far user while improving the near user's rate. To enhance the performance of the QoS provisioning AS scheme, the idea of dynamic antenna clustering is applied at the relay to adaptively partition the relay's antennas into transmit and receive subsets. The proposed AS schemes' exact outage probability and achievable rate expressions are derived. To provide more insight, closed-form asymptotic outage probability expressions for the max-U1 and max-U2 AS schemes are obtained. Our results show that while the QoS provisioning AS scheme can deliver a near-optimal performance for static antenna setup at the relay, it provides up to 12% average sum rate gain over the optimum AS selection with fixed antenna setup.

“…In this regard, recent papers are pushing the research ahead by going beyond that assumption. Recently, some works tried to investigate the performance degradation that occurs due to imperfect SIC (I-SIC) [3]- [6]. However, the existing contributions exploring CUR-NOMA mainly focus on single-carrier scenarios.…”

Cell-edge users of the future cellular internet of things (IoT) with massive IoT sensors can suffer from extremely severe channel conditions, especially under very high-speed scenarios. In this paper, we present a performance improvement method for cell-edge users of multi-carrier modulation (MCM)-based non-orthogonal multiple access (NOMA) downlink systems. To this end, we consider the implementation of cooperative user relaying NOMA (CUR-NOMA) and derive its lower bound E2E-BER under doubly selective channels. In addition, the imperfect successive interference cancellation (SIC) process is analyzed, wherein two interference cancellation schemes are combined to remove the NOMA induced inter-user interference (IUI) and the doubly selective channel induced inter-carrier interference (ICI).

“…In [7], the outage probability of the cognitive radio NOMA network is analyzed under HWI, ICSI and imperfect successive interference cancellation (ipSIC). On the other hand, BER performances of FD-CNOMA have been investigated in [8] with ipSIC where perfect CSI and no HWI are considered. Then, the BER and outage probability performances of a multi-hop decode-and-forward (DF) CNOMA with ICSI has been investigated in [9].…”

Non-orthogonal multiple access (NOMA) has been a strong candidate to support massive connectivity in future wireless networks. In this regard, its implementation into cooperative relaying, named cooperative-NOMA (CNOMA), has received tremendous attention by researchers. However, most of the existing CNOMA studies have failed to address practical constraints since they assume ideal conditions. Particularly, error performance of CNOMA schemes with imperfections has not been investigated, yet. In this letter, we provide an analytical framework for error performance of CNOMA schemes under practical assumptions where we take into account imperfect successive interference canceler (SIC), imperfect channel estimation (ICSI), and hardware impairments (HWI) at the transceivers. We derive bit error rate (BER) expressions in CNOMA schemes whether the direct links between source and users exist or not which is, to the best of the authors' knowledge, the first study in the open literature. For comparisons, we also provide BER expression for downlink NOMA with practical constraints which has also not been given in literature, yet. The theoretical BER expressions are validated with computer simulations where the perfect-match is observed. Finally, we discuss the effects of the system parameters (e.g., power allocation, HWI level) on the performance of CNOMA schemes to reveal fruitful insights for the society.
