چکیده
Non-orthogonal multiple access (NOMA) is a Fifth Generation (5G) technique that allows many users to simultaneously the same time–frequency separating channels via successive interference cancellation (SIC) receiver. Cooperative NOMA (CNOMA) an effective tool prevent performance degradation of far by allocating minimal power with good channel conditions. In this paper, we proposed fair and allocation scheme based on Nash bargaining solution (NBS) game in full-duplex, cooperative beamforming (BF) for multicarrier (MC) NOMA. The NBS assigns optimal according conditions while maintaining rate amongst users. provides optimum approach maximizing total CNOMA. signal-to-leakage (SLR) ratio precoding considered as design criterion vector towards achieving domain CNOMA players. Simulation results show at BER = $${10}^{-5}$$ , (proposed scheme) improved 2 dB terms Signal-to-Noise Ratio (SNR), compared non-cooperative scheme, 3 multiple-input multiple-output (MIMO-NOMA). Both improvements were result reduction information sharing network. fairness, shown high level fairness 0.8401, other similar approaches literature.

Joint Power Allocation and Beamforming for Non-Orthogonal Multiple Access (NOMA) in 5G Millimeter-Wave Communications
In this paper we explore non-orthogonal multiple access (NOMA) in millimeter-wave (mmWave) communications (mmWave-NOMA). In particular, we consider a typical problem, i.e., maximization of the sum rate of a 2-user mmWave-NOMA system. In this problem, we need to find the beamforming vector to steer towards the two users simultaneously subject to an analog beamforming structure, while allocating ...

Carrier aggregation (CA) is considered to be a potential technology in next generation wireless communications. While boosting system throughput, CA has also put forward challenges to the resource allocation problems. In this paper, we firstly construct the energy efficiency optimization problem and prove that the function is strictly quasi concave. Then we propose a binary search-based power a...

In this paper, we investigate power allocation problem with the use of transmit beamforming in a dual hop MISO (multiple input single output) relay channel. We consider either amplify and forward (AF) or decode and forward (DF) cooperative protocols at the relay and optimize the power allocated to the relay and the source, under total transmit power constraint, to minimize the bit error rate (B...
