Deep Reinforcement Learning Based Joint Allocation Scheme in a TWDM-PON-Based mMIMO Fronthaul Network

IEEE Photonics Journal
In next-generation centralized or cloud radio access networks (C-RANs), time and wavelength division multiplexed passive optical network (TWDM-PON) has been well recognized as a promising candidate to build the mobile fronthaul. Considering the stringent

Bandwidth allocation in the NEPHELE hybrid optical interconnect [PDF]

2016 18th International Conference on Transparent Optical Networks (ICTON), 2016
The NEPHELE network is divided into pods of racks and relies on hybrid electro-optical top-of rack switches that access an all-optical network. To enable dynamic and efficient sharing of the optical resources and a collision-free network operation, the NEPHELE network is envisioned to be operated in a slotted TDMA manner with a software-defined-network

Metasurface Doppler Cloak for Broadband Radar Stealth

Advanced Physics Research, EarlyView.
Suppressing the motion‐induced Doppler shift passes the target as part of the static clutter which is ignored by radars. Using a simple time‐modulation, frequency conversion is obtained from a metasurface‐based solution over a wide range. Referred to as a Doppler cloak, this work expands and validates such a varactor‐loaded prototype for broadband ...

Distributed wireless network resource optimisation method based on mobile edge computing

IET Networks, EarlyView., 2022
This paper mainly compares the network ranking leader, consumption amount and network signal reception of the three algorithms. The study found that in terms of network sort captain, there are significant differences between the CPLEX algorithm, the CCST algorithm, and edge computing methods. The CCST algorithm and edge computing have little difference
