In wireless communication, Full-Duplex (FD) is regarded as a crucial method for boosting spectral efficiency. An inexpensive passive reflecting array called Intelligent Reflecting Surface (IRS) utilized to increase Another interesting approach Non-Orthogonal Multiple Access (NOMA), which also increases efficiency by enabling simultaneous transmission of users’ data at the same frequency. The co...

Next-generation satellite systems require more flexibility in resource management such that available radio resources can be dynamically allocated to meet time-varying and non-uniform traffic demands. Considering potential benefits of beam hopping (BH) non-orthogonal multiple access (NOMA), we exploit the time-domain multi-beam by optimizing BH design, enhance power-domain via NOMA. In this pap...

This paper focuses on the non-orthogonal multiple access (NOMA) design for a classical two-user multiple access channel (MAC) with finite-alphabet inputs. In contrast to most of existing NOMA designs using continuous Gaussian input distributions, we consider practical quadrature amplitude modulation (QAM) constellations at both transmitters, the sizes of which are assumed to be not necessarily ...

The high spectrum efficiency of nonorthogonal multiple access (NOMA) is attractive to solve the massive number connections in Internet Things (IoT). This article investigates a buffer-aided cooperative NOMA (C-NOMA) system IoT, where intended users are equipped with buffers for cooperation. direct transmission from point and between coordinated. In particular, novel C-NOMA scheme proposed adapt...

In this work, we address the problem of finding globally optimal power allocation strategies to maximize users sum-rate (SR) as well system energy efficiency (EE) in downlink single-cell multicarrier non-orthogonal multiple access (MC-NOMA) systems. Each NOMA cluster includes a set which well-known superposition coding (SC) combined with successive interference cancellation (SIC) technique is a...

To cope with the explosive traffic growth expected in next-generation wireless networks, it is necessary to design multiple access techniques that can provide higher spectral efficiency as well larger-scale connectivity. As a promising candidate, power-domain non-orthogonal (NOMA) has been widely studied. In conventional NOMA, users are multiplexed same time and frequency band different <italic...

In this issue of Cell, Noma et al. (2006) show that B-boxes and TFIIIC limit the spread of heterochromatin at the silent mat region in the fission yeast genome. Global analysis of TFIIIC distribution revealed dispersed sites of association that coalesce at the nuclear periphery, suggesting that TFIIIC may act as a barrier throughout the genome.

Objectives: In this work, we investigate suitable techniques to reduce the Peak Average Power Ratio (PAPR) for advanced modulation schemes in order obtain better performance than current or commonly used Fourth Generation (4G) and Fifth (5G). Methods: The proposed scheme incorporates a combination of Selective Mapping (SLM) Partial Transmission Scheme (PTS) thereby efficiently minimizes PAPR co...
