Journal of Electrical and Computer Engineering, Volume 2023, Issue 1, 2023., 2023 Noise in a communication system degrades the signal level at the receiver, and as a result, the signal is not properly recovered or eliminated at the receiver side. To avoid this, it is necessary to modify the signal before transmission, which is achieved using channel coding.

Optimizing Nonlinear Distortion and Interference in MC‐CDMA Receivers Employing Deep Neural Networks
Mobile Information Systems, Volume 2023, Issue 1, 2023., 2023 Systems that employ multicarrier code division multiple access, commonly known as MC‐CDMA, produce outstanding results in terms of both the performance of the system as a whole and the efficiency with which it uses the spectrum. However, multiple access strategies are susceptible to interference despite their high spectrum efficiency. This work aims to

A Tutorial on IEEE 802.11ax High Efficiency WLANs [PDF]
IEEE Communications Surveys & Tutorials, 2019 While celebrating the 21st year since the very first IEEE 802.11 “legacy” 2 Mbit/s wireless local area network standard, the latest Wi-Fi newborn is today reaching the finish line, topping the remarkable speed of 10 Gbit/s. IEEE 802.11ax was launched in May 2014 with the goal of enhancing throughput-per-area in high-density scenarios.

Design and Characterization of a Compact Four‐Element Microstrip Array Antenna for WiFi‐5/6 Routers
International Journal of RF and Microwave Computer-Aided Engineering, Volume 2023, Issue 1, 2023., 2023 The WiFi‐5 band was the most popular WiFi band until the Federal Communications Commission (FCC) announced a new spectrum of 6 GHz WiFi (5.925–7.125 GHz) for unlicensed users. Our proposed work is about to cover both the 5 GHz and 6 GHz WiFi bands. These two bands have a great impact in the wireless communication field.

Engineering Reports, Volume 4, Issue 11, November 2022., 2022 We established Linear WANET model on the NS‐3 network simulator to perform A‐MSDU, A‐MPDU, and two‐level frame aggregation simulation and analyzed the aggregation performance under different channel environments. The RTS/CTS and TXOP mechanisms were also simulated in this article.

Target Wake Time: Scheduled Access in IEEE 802.11ax WLANs [PDF]
IEEE Wireless Communications, 2019 The increasing interest for ubiquitous networking, and the tremendous popularity gained by IEEE 802.11 Wireless Local Area Networks (WLANs) in recent years, is leading to very dense deployments where high levels of channel contention may prevent to meet the increasing users' demands.

[Retracted] Smart System Resource Coordination Algorithm Based on 6G Technology
Journal of Electrical and Computer Engineering, Volume 2022, Issue 1, 2022., 2022 Most of the existing resource allocation algorithms do not take into account the restriction conditions such as the delay limitation of different services and the service volume requirements of different STAs. Moreover, the surge in the number of smart terminal devices has brought great challenges to the access effect of WLAN systems.

Performance Analysis of Synchronous Multilink MAC Protocol with Automatic Repeat Request
Mobile Information Systems, Volume 2022, Issue 1, 2022., 2022 Multilink operation (MLO) is considered a key candidate technique in 802.11be, which allows devices to transmit and receive data using multiple links concurrently, thereby contributing to improving throughput and reducing latency. However, the performance of the MLO scheme will gradually degrade as the channel environment deteriorates.

Wireless Communications and Mobile Computing, Volume 2022, Issue 1, 2022., 2022 Channel bonding is considered by the IEEE 802.11ac amendment to improve wireless local area network (WLAN) performance. In this article, the channel bonding and aggregation method were proposed to increase wireless local area network performance (WLANs). It combines many channels (or lanes) to boost the capacity of modem traffic. Channel bonding is the
