In this paper, a downlink non-orthogonal multiple access (NOMA) network with two users is considered. In particular, the performance of NOMA is evaluated by assuming perfect and imperfect channel state information (CSI). We derive the closed-form exp

In this paper, the impact of the non-linearity of the propagation medium on the extended $\eta $ - $\mu $ fading distribution is studied. In particular, the extended $\alpha $ - $\eta $ - $\mu $ fading model in which the parameter $\alpha $ represent

This paper proposes novel and generalized expressions to characterize the performance of modern cellular networks under realistic user mobility behavior. The η-μ distribution is employed to derive the received power probability density function, th

In this paper, we propose a relay-assisted device-to-device (D2D) communication as an underlay in a cellular network, where two sequential best relay nodes based on different selection criteria are chosen. Novel analytical expressions of the secrecy

In this paper, a partially overlapped near user non-orthogonal multiple access (P-N-NOMA) scheme is proposed in which the signal of near user is partially overlapped rather than a complete overlapping as in conventional NOMA (C-NOMA). This research i

Abstract In this paper, signal-to-noise ratio (SNR) estimation is carried out by the method of moments (MOM) for fading channels modeled by probability distributions η−μ and κ−μ, considering M-ary quadrature amplitude modulation (M-QAM) with

Transmission in non-line-of-sight (NLOS) conditions has a poor throughput in device-to-device (D2D) communications. In order to achieve high throughput, adaptive modulation has been selected as a spectrally-efficient transmission technology. Moreover
