Best insight from top research papers
Cooperative NOMA with multi-relays can be used to improve the performance of other wireless communication techniques. It allows network nodes to cooperate and take advantage of the broadcast aspect of wireless channels, resulting in increased transmission. MUD is a cooperative transmission protocol that offers good spectrum efficiency, diversity gain, and coding gain . By completely exploiting the link between the relay and the destination, high diversity order and coding gain can be achieved, benefiting all users . Additionally, multi-hop user relays assisted NOMA can combat channel disorders, extend coverage area, and improve quality of service (QoS) . Theoretical analyses and computer simulations have shown that the performance of cooperative NOMA with multi-relays deteriorates as the number of hops increases, but it still offers advantages in terms of BER and OP performance . Therefore, cooperative NOMA with multi-relays can be a promising technique to enhance the performance of wireless communication systems.

How does the use of NOMA impact the performance of wireless communication systems in terms of throughput and fairness?5 answersThe utilization of Non-Orthogonal Multiple Access (NOMA) in wireless communication systems significantly enhances throughput performance. NOMA technology not only aims at maximizing throughput but also addresses the crucial aspect of ensuring fairness among different wireless devices (WDs) in the network. By implementing NOMA, the sum-throughput of the system can be improved while guaranteeing individual WDs' throughput levels, thus balancing performance across devices. Additionally, NOMA aids in managing inter-functionality interference, maximizing computation offloading capacity, and enhancing overall spectral efficiency in multi-tier computing structures. Therefore, NOMA plays a vital role in enhancing both throughput and fairness aspects of wireless communication systems, making it a promising technology for future network deployments.
How does NOMA improve the efficiency and capacity of 5G networks compared to traditional orthogonal multiple access methods?4 answersNon-orthogonal multiple access (NOMA) improves the efficiency and capacity of 5G networks compared to traditional orthogonal multiple access (OMA) methods. NOMA achieves higher spectrum efficiency and average capacity by allowing multiple users to transmit and receive simultaneously using the same frequency. It combines NOMA with technologies like multiple-input and multiple-output (MIMO) and massive MIMO (M-MIMO) to further enhance capacity. The integration of NOMA with cooperative cognitive radio networks (CCRN) and the use of dedicated channels (D-CH) or competing channels (C-CH) in the power domain (PD) also contribute to improved efficiency. The results show that NOMA outperforms OMA in terms of user productivity, capacity, energy efficiency, and the number of users. It provides higher average capacity and spectral efficiency, although it may be more sensitive to bit error rate.
What is the latest Multiple access scheme?5 answersThe latest multiple access scheme is Rate Splitting Multiple Access (RSMA). RSMA is a generalized multiple access scheme that aims to enhance spectral resource utilization and achieve a promising multiplexing gain. It is presented as an improvement over orthogonal multiple access (OMA) schemes such as frequency division multiple access (FDMA), time division multiple access (TDMA), and code division multiple access (CDMA). RSMA provides better spectrum efficiency (SE) compared to OMA, space division multiple access (SDMA), and non-orthogonal multiple access (NOMA) techniques. It addresses the limitations of multiplexing gain in NOMA schemes by allowing users to transmit their data streams simultaneously under maximum capacity constraints. RSMA offers advantages in terms of SE, scalability, delay, and energy efficiency (EE) in fifth generation (5G) networks.
How can cooperative competition be used to increase the efficiency of a system?5 answersCooperative competition can be used to increase the efficiency of a system by promoting collaboration and maximizing market sales. By applying cooperative strategies based on altruistic behavior, members of a supply chain can improve economic benefits for all parties involved. This can be achieved by establishing equilibrium strategies and optimizing the channel efficiency of the supply chain. Additionally, competition between projects can be designed to create conditions for socially optimal outcomes, leading to efficient equilibrium. In the context of corporate culture, competition can lead to better coordination and higher rates of cooperation, resulting in improved performance outcomes. Furthermore, competition between school systems can incentivize school managers to increase effort and improve test score gains. Overall, cooperative competition can drive collaboration, coordination, and improved performance, leading to increased efficiency in various systems.
