Coaxial Networks for 5G Fronthaul
2018 IEEE 23rd International Workshop on Computer Aided Modeling and Design of Communication Links and Networks (CAMAD), 2018In this paper, we present an investigation about the potential of coaxial networks for 5G fronthaul. The study is motivated since some countries have a big coaxial infrastructure that could potentially be used for 5G applications. In this context, we propose here a fronthaul scheme with analog radio over coaxial cables and evaluate the maximum number ...

Joint Design of Fronthaul and Access Links for C-RAN With Wireless Fronthauling
IEEE Signal Processing Letters, 2016This letter studies a joint design of fronthaul and radio access links for a cloud radio access network (C-RAN) with wireless fronthauling, where a baseband unit (BBU) controls a number of remote radio heads (RRHs) via wireless fronthaul links to communicate with user equipments.

Optical Fiber Communications Conference and Exhibition, 2023
We review recent advances in the mitigation of inter-channel four-wave-mixing (FWM) based on the "XYYX" input polarization alignment and unequal channel spacing to enable high-performance O-band WDM transmission for 800G-LR4, 1.6T-LR8 and bidirectional ...
