Joint power allocation for MIMO-OFDM full-duplex relaying communications

In this paper, we address the problem of joint power allocation in a two-hop MIMO-OFDM network, where two full-duplex users communicate with each other via an amplify-and-forward relay. We consider a general model in which the full-duplex relay can forward the received message in either one-way or two-way mode. Our aim is to maximize the instantaneous end-to-end total throughput, subject to (i)...

Wind Farms Site Selection and Allocation In Power Distribution Network Using GIS and Optimization Algorithm

Increasing demand for electricity and consequently running out of fossil fuel resources and negative impact of fossil fuels on the environment has led to the need for finding renewable energy sources. Iran has high potentiality in exploiting  wind energy because of its topology and various climatic conditions. For this purpose, optimal places for installing these facilities should be determined...

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 ...

Secure Communications in NOMA System: Subcarrier Assignment and Power Allocation

Secure communication is a promising technology for wireless networks because it ensures secure transmission of information. In this paper, we investigate the joint subcarrier (SC) assignment and power allocation problem for nonorthogonal multiple access (NOMA) amplify-and-forward twoway relay wireless networks, in the presence of eavesdroppers. By exploiting cooperative jamming (CJ) to enhance ...
