In this paper, we aim to design a power allocation strategy to minimize the average
consumed power of a hybrid automatic repeat request with chase combining (HARQ-CC) …

In this letter, we propose a novel dynamic power allocation scheme for hybrid non-
orthogonal multiple access (DH-NOMA). The exact expressions for the outage probabilities …

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 a multiple access technology that can provide
efficient spectrum utilization and increased channel capacity on Internet of Things (IoT) …

In a device-to-device communication scenario, the number of far users (FUs) is higher than
the near users (NUs) in each cluster. In such a scenario, the paired NUs and FUs …

Uplink non-orthogonal multiple access (NOMA) is a promising technique to meet the
requirements of the fifth generation (5G) and beyond systems. Various NOMA schemes have …

The novel concept of near-field non-orthogonal multiple access (NF-NOMA)
communications is proposed. The near-filed beamfocusing enables NOMA to be carried out …

As energy efficiency (EE) is a key performance indicator for the future wireless network, it
has become a significant research field in communication networks. In this paper, we …

Non-orthogonal multiple access (NOMA) and cognitive radio (CR) are envisioned as
promising solutions to achieve high spectral efficiency for future wireless networks. This …

In this letter, we exploit constellation rotation to enhance the performance of uplink non-
orthogonal multiple access (NOMA) with a successive interference cancellation receiver. We …
