Transformer-Based High-Fidelity Modeling Method for Radio Over Fiber Link

Journal of Lightwave Technology, 2023
High-fidelity modeling is of great importance for digital twin (DT) technology. A Transformer-based modeling method for radio over fiber (RoF) link is developed and experimentally demonstrated, in which the Transformer is a kind of deep learning network.

Linearization Schemes for Radio Over Fiber Systems Based on Machine Learning Algorithms

IEEE Photonics Technology Letters, 2022
This work is regarding the concept and implementation of pre- and post-distortion schemes idealized for radio-over-fiber (RoF) systems. Analog RoF systems have been considered potential to increase the capillarity of future mobile networks.

High-performance dual-band radio-over-fiber link for future 5G radio access applications

Journal of Optical Communications and Networking, 2022
For the fronthaul between the baseband unit and the remote radio unit (RRU), radio over fiber (RoF) is promising to replace the Common Public Radio Interface in beyond fifth-generation and the sixth-generation wireless communication systems.

Radio-Over-Fiber Architectures

IEEE Vehicular Technology Magazine, 2010
Future multigigabit wireless systems (MGWS) dedicated to home-area networking are emerging or are under development. They achieve high data rate up to 5-6 Gb/s over short range. To expand the radio coverage, we propose radio-over-fiber (RoF) architectures, from the most basic (point-to-point) to the most innovative (multipoint-to-multipoint). These RoF

Radio-over-Fiber Transmission Supporting 65536-QAM at 25GHz Band with High-Pass Delta-Sigma Modulation and RF fading Mitigation

Optical Fiber Communications Conference and Exhibition, 2022
We experimentally demonstrate radio-over-fiber transmission of 44.4Gb/s 65536-QAM at 25GHz employing 2-bit high-pass delta-sigma modulation. 0.19% EVM is achieved after 10km C-band SSMF transmission, and dispersion-induced RF fading is mitigated by ...
