This study investigates the bit error rate (BER) performance analysis for both amplify-and-
forward (AF) and decode-and-forward (DF) assisted relay selection algorithms used in …

In this paper, the problem of joint relay selection and energy‐efficient power allocation (J‐
RS‐EE‐PA) in energy‐harvesting cooperative nonorthogonal multiple‐access networks is …

This article investigates the impacts of relay selection schemes on cooperative underlay
cognitive radio non-orthogonal multiple access networks, where the partial relay selection …

In this paper, the problem of joint relay selection and max‐min energy‐efficient power
allocation (J‐RS‐MMEE‐PA) in downlink multicell nonorthogonal multiple access (NOMA) …

In this paper, we derive the effect of channel errors on the performance of user relaying
cooperative NOMA system in closed-form. The max-min selection strategy is adapted to the …

In this paper, we study a cooperative non-orthogonal multiple access (NOMA) system
underlying cognitive networks which adapt user relaying and selection combining. The …

Recently, Non-orthogonal multiple access (NOMA) has been focused for the next generation
multiple access, which has more spectral efficiency under the limited spectrum bandwidth …
