Performance evaluation of uplink NOMA in Wi-Fi networks
P. 1–5.
© 2020 IEEE.Non-orthogonal multiple access (NOMA) is a key technology for future wireless systems. Keeping the number of antennas on the devices unchanged, NOMA increases the spectral efficiency of the wireless system and raises the aggregated system throughput. For this reason, NOMA is a very attractive technology for implementation in future Wi-Fi standards that will come after Wi-Fi 7. The paper proposes and evaluates uplink NOMA in Wi-Fi, The obtained results show approximately 100% gain in throughput of the uplink NOMA comparing with the legacy Wi-Fi systems.

Постановка проблемы. Во все времена информация являлась востребованным ресурсом. Злоумышленники, захватывая данные, в некоторых случаях могли существенно влиять не только на отдельные объекты и процессы, но и на развитие социума. Современный мир нельзя представить без беспроводных способов связи. Множество электронных устройств передают данные между собой с помощью различных протоколов, и, к сожалению, эти протоколы не ...

This article studies the performance of wholesale pricing when the supply chain partners' fairness concerns are private information. We find that some properties of wholesale pricing established under complete information hold under incomplete information as well. First, wholesale pricing can coordinate the supply chain, despite the information asymmetry, when fairness concerns are strong enough. Second, ...

Various contracts can be designed to coordinate a simple supplier–retailer channel, yet the contracts proposed in prior research and tested in a laboratory setting do not perform as standard theory predicts. The supplier, endowed with all bargaining power, can neither fully coordinate the channel nor extract all of the channel profit. We report on a ...

Problem definition: To improve the poor performance of supply chains caused by misaligned incentives under the wholesale price contract, theory proposes coordinating contracts. However, a common finding of experimental studies testing such contracts is that they tend to yield only a marginal, if any, performance improvement over wholesale pricing. These studies identify several behavioral factors ...

The article offers an analysis of the problems associated with sentencing in the presence of mitigating circumstances. Individualization of punishment is the main narrative of the criminal law institution of sentencing. When determining the measure of punishment, the court does not have the right to ignore circumstances that, without affecting the qualification of the offense, ...

Emerging wireless systems target to provide multi-Gbps data rates for each user, which can be achieved by utilizing ultra-wide channels available at mmWave, terahertz, and lightwave frequencies. In contrast to the traditional spectrum below 6 GHz, these high-frequency bands raise many issues, complicating their usage. For example, because of high signal attenuation and blockage by ...

© 2021 IEEE.Non-Orthogonal Multiple Access (NOMA) is a promising technology for future Wi-Fi, In uplink NOMA, stations with different channel conditions transmit simultaneously at the same frequency by splitting the signal by power level. Since Wi-Fi uses random access, the implementation of uplink NOMA in Wi-Fi faces many challenges. The paper presents a data transmission ...

Non-orthogonal multiple access (NOMA) is a well-accepted technology for future Wi-Fi systems to improve spectral efficiency. NOMA allows an access point (AP) to simultaneously serve multiple devices by splitting the transmit power between them. Using the superposition coding the AP combines signals of different frames with predefined power weights. However, as it is already known, ...

Nowadays, the Direction of Arrival (DoA) estimation problem attracts much attention because of emerging use cases for wireless networks. DoA is beneficial for Reconfigurable IntelligentSurfaces, indoor localization, and various navigation and sensing applications, such as gesture recognition and home monitoring. The Multiple Signal Classification (MUSIC) algorithm is very promising for DoAestimation because it provides better ...

This paper studies the usage of orthogonal frequency division multiple access (OFDMA) for uplink transmissions in IEEE 802.11ax networks. OFDMA enables simultaneous multi-user transmissions in Wi-Fi, but its usage requires efficient resource allocation algorithms. These algorithms should be able to adapt to the changing channel conditions, including the frequency-selective fading. This paper presents an OFDMA ...

New Radio-Unlicensed (NR-U) is a technology that allows fifth generation mobile networks to utilize unlicensed frequency bands, in particular, the 5 GHz band. To increase throughput, an NR-U base station (gNB) can simultaneously operate in several frequency channels within the 5 GHz band. However, the gNB cannot always transmit data through one channel and, at ...
