This paper investigates the optimal power allocation scheme for sum throughput maximization of non-orthogonal multiple access (NOMA) system with α-fairness. In contrast to the existing fairness NOMA models, α-fairness can only utilize a single scalar to achieve different user fairness levels. Two different channel state information at the transmitter (CSIT) assumptions are considered, namely, s...

The orthodox view of the relationship between science and religion, exemplified by Stephen Gould’s “nonoverlapping magisteria” (NOMA) principle 1 is that they are fully compatible and thus can peacefully coexist. This view is exemplified by a National Academy of Sciences pamphlet on Science Evolution and Creationism and a related book by one of its leading authors 3 and it is also eloquently ex...

Non-orthogonal multiple access (NOMA) is emerging as a promising multiple access technology for the 5th generation cellular networks to address the fast growing mobile data traffic. It applies superposition coding in transmitters, allowing simultaneous allocation of the same frequency resource to multiple intra-cell users. Successive interference cancellation is used at the receivers to cancel ...

Cognitive radio (CR) and non-orthogonal multiple access (NOMA) have been deemed two promising technologies due to their potential to achieve high spectral efficiency and massive connectivity. This paper studies a multiple-input singleoutput NOMA CR network relying on simultaneous wireless information and power transfer (SWIPT) conceived for supporting a massive population of power limited batte...

In order to study the therapeutic and developing aspect the child's noma in Burkina Faso, we have undertaken a retrospective study on a ten-years-period, with the files of 59 children hospitalized in the hospital of Bobo-Dioulasso, completed with a visit to the children's families after their leaving the hospital. The medical treatment has allowed to reach a recovery rate of 79.6% at the cost o...

Recently, non-orthogonal multiple access (NOMA) has attracted considerable interest as one of the 5G-defining techniques. However, as NOMA is intrinsically in favour of the transmission of strong users who are capable of carrying out successive decoding, judicious designs are required to guarantee user fairness. In this paper, a two-user downlink NOMA system over fading channels is considered. ...

of the cases of preterm EG in the literature involve the face. This characteristic formed the basis for the term noma neonatorum, coined by Ghosal et al. because of the clinical similarity between this type of EG and noma (cancrum oris), a disease that is predominantly caused by Fusobacterium necrophorum and Prevotella intermedia and described in children aged 2 years and older and adults livin...

Non-orthogonal multiple access (NOMA) is deemed to be a prospective technology of the next generation. However, in visible light communication (VLC), when advanced hybrid optical orthogonal frequency division multiplexing (O-OFDM), such as asymmetrically clipped O-OFDM (HACO-OFDM), combined with NOMA, error propagation induced, which degrades system performance. Therefore, novel reconstructed O...

This case report describes a 4-year-old girl in Chad with noma, also called cancrum oris. This acute gangrenous stomatitis has a combined morbidity-mortality rate that can reach 70%. It occurs worldwide but is most common in sub-Saharan Africa in children aged 2 to 16 years. Its pathogenesis is uncertain, but several bacteria including Fusobacterium necrophorum, Prevotella intermedia and Pseudo...

In this paper, a multipoint-to-point system consisting K users and a central node with non-orthogonal multiple access (NOMA) technique over free space optical (FSO) channel is characterized for two cases. In the case of guaranteed user's quality of service (QoS), the outage probability is derived. Another case is that user's QoS is determined by their own channel conditions. The developed analy...
