Millimeter‐Wave Antennas: A Comprehensive State‐of‐the‐Art Review of Design Approaches, Operating Bands, Challenges, and Applications in Body‐Centric and Emerging Systems

Radio Science, Volume 61, Issue 5, May 2026.
Abstract This paper reviews and classifies more than 120 recent contributions on millimeter‐wave (mm‐wave) antennas, with emphasis on their operating bands, design methods, and application domains. It surveys the main mm‐wave frequency ranges and their use in 5G/6G communications, radar and sensing, biomedical and body‐centric systems, imaging, and ...

Dataplane Measurements On A Fronthaul And Backhaul Integrated Network

, 2017
Future transport networks serving next generation accesses are expected to carry both fronthaul (FH) and backhaul (BH) traffic simultaneously. This new concept of network which integrates the FH and BH traffic over the same transport substrate is called Crosshaul.

Fronthaul compression and optimization for cloud radio access networks [PDF]

2016 IEEE International Conference on Communications (ICC), 2016
In the present paper, we investigate the design and optimization for fronhaul links in cloud radio access networks (C-RAN). Existing C-RAN designs rely on the instantaneous network-wide channel state information (CSI), which might impose a significant overhead due to the potential large-scale of C-RAN.

Framework for Task Offloading in O‐RAN Architecture for Heterogeneous Computing Applications

Transactions on Emerging Telecommunications Technologies, Volume 37, Issue 2, February 2026.
This work proposes a task offloading framework in ORAN architecture, optimizing computational assignment across user devices, edge cloud, and regional cloud. By efficiently selecting processing nodes and allocating computational and radio resources, it minimizes delay while accommodating diverse latency requirements for gold, silver, and bronze‐tier ...

An Elastic Optical Network-based Architecture for the 5G Fronthaul

Anais do XXXVI Simpósio Brasileiro de Redes de Computadores e Sistemas Distribuídos (SBRC 2018), 2018
In 5G networks, the traffic demands are expected to increase significantly. To deal with this problem, many research efforts focus on TWDMPON for the fronthaul. However, TWDM-PON suffers from the issue of wasted bandwidth when a demand is smaller than the channel.

First Real‐Time Softwarization of Complete Coherent DSP Stack with Gardner Timing and Clock Recovery

Electronics Letters, Volume 62, Issue 1, January/December 2026.
ABSTRACT This work demonstrates the first fully softwarized coherent receiver digital signal processing stack implemented on a general‐purpose graphic processing unit (GPU) platform. By introducing a data‐parallel GPU implementation for Gardner‐based timing and clock recovery (TCR), the system achieves complete real‐time receiver operation without ...
