Owing to the increasing demand of higher spectrum efficiency and large-scale connectivity, non-orthogonal multiple access (NOMA) has become a highly competitive candidate for upcoming sixth-generation (6G) systems. Nevertheless, instable wireless propagation environment potential security risk bottlenecks in applications NOMA. Fortunately, intelligent reflecting surface (IRS) that can construct...

In a recent article in the Jpn J Physiol Matsuoka et al. [1] present in their discussion section a comparison of their cardiac action potential model and the Luo-Rudy dynamic (LRd) model [2]. Figure 10 in their paper compares the action potential (AP), calcium transient (CaT) and selected ionic currents during the AP. Several results of their LRd simulations are conducted using parameters/proto...

In this paper, the physical layer security of uplink non-orthogonal multiple access (NOMA) in large-scale networks is analyzed. An stochastic geometry approach is applied to derive new analytical expressions for the coverage probability and the effective secrecy throughput (EST) of the kth NOMA user, which may use a fixed or an adaptive transmission rate. We consider a protected zone around the...

Noma (cancrum oris) is a disease of poverty and malnutrition, which predominantly affects children younger than 10 years in developing countries. Although the majority of sufferers die of sepsis at the time of the initial infection, or of subsequent starvation due to severe trismus and an inability to eat, a small minority of patients survive and require reconstructive surgery for severe facial...

In this paper, cooperative non-orthogonal multiple access (C-NOMA) is considered in short packet communications with finite blocklength (FBL) codes. The performance of a decode-and-forward (DF) relaying along selection combining (SC) and maximum ratio (MRC) strategies at the receiver side examined. We explore joint user pairing resource allocation to maximize fair throughput downlink (DL) scena...

Non-orthogonal multiple access (NOMA) technique and unmanned aerial vehicles (UAVs) have been recognized as promising technologies for enabling the stringent requirements of different network infrastructures expected next generation wireless networks. In parallel, intelligent reconfigurable surfaces (IRSs) widely pointed out an auspicious solution to further improve spectral efficiency, coverag...

Filtered Non-Orthogonal Multiple Access (F-NOMA) is a multi-carrier wave form and considered suitable contender for 5G radio. Peak to average power ratio (PAPR) regarded as major hurdle in the NOMA because it hampers efficiency of amplifier transmitter. In this study, novel selective mapping (SLM) algorithm used minimize PAPR NOMA. The conventional SLM increases intricacy structure, projected a...

In this paper, we investigate the dynamic power allocation for a visible light communication (VLC) cellular system consisting of two coordinating attocells, each equipped with one access-point (AP). The coordinated multipoint (CoMP) between cells is introduced to assist users experiencing high inter-cell-interference (ICI). Specifically, zero-forcing (ZF) precoding used cancel ICI at located ne...
