All-Optical Network Capacity for 5G Cellular Fronthaul

2019 21st International Conference on Transparent Optical Networks (ICTON), 2019
In this paper, we have investigated the use of fast wavelength switching optical transmitters and a wavelength selective space switching all-optical network for cellular fronthaul applications. System capacity is calculated by using hard-deadlines that arise from the radio requirements and the physical constraints of the optical network.

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 ...

Access Point Selection and Localization for Cluster‐Based Realization of a Device‐to‐Device Cell‐Free 6G Communications Network

IET Communications, Volume 19, Issue 1, January/December 2025.
We introduce a fully distributed framework that leverages belief‐desire‐intention extended (BDIx) agents on user devices to perform dynamic clustering and access‐point selection in a cell‐free 6G network, using both classical and deep‐learning methods for deterministic, scalable AP grouping.

Sequential In-Network Processing for Cell-Free Massive MIMO With Capacity-Constrained Parallel Radio Stripes

IEEE Access
To ensure coherent signal processing across distributed Access Points (APs) in Cell-Free Massive Multiple-Input Multiple-Output (CF-mMIMO) systems, a fronthaul connection between the APs and a Central Processor (CP) is imperative. We consider a fronthaul

Downlink Power Control for Cell‐Free Massive MIMO System With Radio Stripes

Electronics Letters, Volume 61, Issue 1, January/December 2025.
This paper investigates downlink power control in cell‐free massive multiple‐input multiple‐output systems utilizing radio stripes, a cost‐effective fronthaul topology. An AP switching technique is proposed to enhance spectral efficiency, followed by the formulation of a weighted sum‐rate maximization problem considering QoS, transmit power, and user ...
