This letter applies non-orthogonal multiple access to uplink random access systems, where
the transmit power from each user equipment (UE) is received at the base station as one of L …

Conventional non-orthogonal multiple access (NOMA) schemes assume perfect channel
state information (CSI) at the transmitter side, which is nearly impractical for many …

We propose a tractable expression for the outage probability in single-cell uplink non-
orthogonal multiple access (NOMA) systems serving an arbitrary number of users. The …

The performance of non-orthogonal multiple access (NOMA) is investigated in a cellular
downlink scenario with randomly deployed users. The developed analytical results show …

In this study, non‐orthogonal multiple access (NOMA) is considered for multiusers wireless
communications over Rayleigh fading channel. The base station (BS) utilises NOMA …

Non-orthogonal multiple access (NOMA) is currently considered as a promising technology
for the next-generation wireless networks. In this paper, the error rate performance of NOMA …

In this letter, an adaptive power allocation (APA) strategy is proposed for an uplink non-
orthogonal multiple access (NOMA) with semi-grant-free (SGF) transmission, where one …

In nonorthogonal multiple access (NOMA), the power difference of multiple signals is
exploited for multiple access and successive interference cancellation is employed at a …

In sixth generation (6 G) networks, a massive number of users and devices must be
connected, necessitating flexible resource allocation. In this context, non-orthogonal multiple …

In this work, the performance of the downlink non-orthogonal multiple access (NOMA)
technique is investigated for two users considering optimal power allocation factors. The …
