Performance Analysis of Power Control Algorithms in Uplink Cell‐Free Massive MIMO Systems

Journal of Engineering, Volume 2026, Issue 1, 2026.
Cellular massive multiple input multiple output (MIMO) technology has revolutionized wireless communication by enhancing spectral efficiency (SE). However, its ability to meet the growing data rate demands of future networks beyond fifth generation (5G) is limited by challenges like intercell interference.

Optical Wireless Communications with Metasurfaces: Current Status and Potential for Intelligent Communications

Advanced Photonics Research, Volume 6, Issue 7, July 2025.
Optical wireless communications (OWCs) provide a promising alternative to spectrum‐congested microwave wireless communications. Recently, the use of metasurfaces with sub‐wavelength features for dynamic beam steering, beam manipulation, and spatial or optical‐angular‐momentum mode generation, conversion, and multiplexing in OWCs is proposed and ...

SDN-based management of time-sensitive networks in 5G fronthaul

, 2018
Software Defined Networking is a key element in the 5G architecture, as it allows a more flexible, dynamic network management. Cloud RAN is another enabler of 5G, due to the expected increased based station density in the fronthaul.

UAVs‐Assisted Low‐Bit Quantized CF‐mMIMO Systems With MmWave Communications Under MRC Detection

IET Communications, Volume 19, Issue 1, January/December 2025.
ABSTRACT The cell‐free massive multiple input multiple output (CF‐mMIMO) approach, due to its high coverage and the ability to attenuate the large‐scale fading impacts in wireless communications, has drawn a lot of attention. Additionally, because of their movement ability, low power, and low‐cost employed infrastructures, unmanned aerial vehicles ...
