Non-orthogonal multiple access (NOMA) is a Fifth Generation (5G) technique that allows many users to simultaneously access the same time-frequency separating channels via successive interference cancellation (SIC) receiver. Cooperative NOMA (CNOMA) is an effective tool to prevent performance degradation of far users by allocating minimal power to users with good channel conditions. In this paper, we proposed a fair power and channel allocation scheme based on the Nash bargaining solution (NBS) game solution in full-duplex, cooperative beamforming (BF) for multicarrier (MC) NOMA. The proposed NBS scheme assigns optimal power and channel allocation according to channel conditions while maintaining a fair rate amongst cooperative users. NBS provides a fair and optimum approach for maximizing the total rate of CNOMA. The signal-to-leakage (SLR) ratio precoding technique is considered as a design performance criterion for beamforming vector towards achieving power domain CNOMA players. Simulation results show that at BER = − , the NBS power allocation (proposed scheme) improved by 2 dB in terms of Signal-to-Noise Ratio (SNR) , compared with the non-cooperative scheme, and 3 dB compared with the multiple-input multiple-output NOMA (MIMO-NOMA). In terms of fairness, the proposed NBS scheme shown a high level of fairness at 0.8401, compared to the other similar approaches in the literature.

“…Orthogonal signalling, such as frequency division multiple access and time division multiple access, converts the non-convex utility space to a convex one, which is considered a drawback of using NBS [19] with NOMA. Thus, in this study, we adopt signal-to-leakage ratio (SLR) [20][21][22] as a beamforming vector in order to:…”

“…However, the main issues considered in these publications mainly concern to decoding features of structured LDPC-codes, turbo-codes, BCH-codes and others [9]. In papers [10,14,15] authors provide recommendations on the features of iteration process in decoding, and consider efficient multi-threshold decoding algorithms for wireless channels [16]. Detailed research of advantages of multi-threshold decoding in a binary erasure channel is provided in [15].…”

<p>The methodology description of the adaptive multi-threshold decoding of self-orthogonal codes in the telecommunication channels of information transfer is shown in this paper. The method of multi-threshold decoder modification is described on the basis of adaptive filtration algorithms. Principles of adaptive algorithms application provide for necessary data transmission validity in the case of the multi-threshold decoding are explored. The graphic charts of multi-threshold decoders noise immunity of self-orthogonal block and convolutional codes are presented. It is determined the coding gain (CG) for multi-threshold decoding schemes. The result of research conducted in the course of the paper is to develop a set of scientifically grounded theoretical positions and practical recommendations and proposals for the development of mechanisms of formalization of description of method of increasing of noise immunity of telecommunication systems transmitting information to the synthesis and improving receiver circuit modulated signals on the theory and practice the use of signal-code constructions (SCC) when deciding maximize system capacity information transmission in the presence of noise.</p>

“…Therefore, a RN can adequately expand the sign and administration inclusion of an eNB and improve the general throughput execution of a remote correspondence framework and explain the previously mentioned low SNR issue. Transferring innovation can likewise be incorporated in ordinary base station stages, which is cost effective and simple to convey as it does not require extra back take [14].This paper centers around assessing the exhibition of an LTE Advanced system with Relay Nodes on urban smaller scale cells. For that we investigate the thought and hypothesis of LTE Advanced and WINNER channel model to make a reenactment model, which is equipped for assessing the presentation of hand-off sending in an LTE-Advanced using the WINNER channel model [15], [16] [17].…”

Cooperative Relay is a promising enhancement to modern radio technologies which has been considered in LTE-Advanced and IEEE 802.16m technologies. Cooperative Relay is one of the technologies that used to improve coverage in downlink mobile network. The work is done by designing numerous environments for LTE-Advanced networks involving relays, whereby using vertical distributions of relays for both AAF & DAF techniques as well as comparison between the performances optimal of both techniques on urban micro cell for LTE-Advanced Technologies, Insertion the channel model from WINNER project. The performances optimal of non-Cooperative Relay and Cooperative Relay are evaluated in terms of Symbol Error Rate (SER) and Signal-to Noise-Ratio (SNR). The simulation results show that relay technologies can effectively improve system performance. On the other hand, 10-Relay in vertical distributions clearly shows outperforms on other environments and, when the relay put near, middle and far from Evolved Node B (eNB), the result shows at SER of 10-3 the system that employs AAF technique outperforms on the system that employs DAF technique in LTE-A system by about 6.5 dB, 2.5 dB and 2 dB sequent.
