TL;DR: A novel scheme to effectively mitigate the nonlinear impairments in a PAM-8 radio-over-fiber (ROF) delivery is proposed by a joint deep neuron network (J-DNN) equalizer, which has more superiority in terms of good training accuracy, satisfactory tracking speed, and over-fitting suppression compared with a typical deep neurons network (DNN).
Proceedings ArticleDOI
A survivable protection and restoration scheme using wavelength switching of integrated tunable optical transmitter for high throughput WDM-PON system
TL;DR: A survivable protection and restoration mechanism is proposed using wavelength switching of low-cost integrated tunable laser assembly to protect multiple fiber failures in a high capacity colorless WDM-PON.
Journal ArticleDOI
Photonic Vector Signal Generation Employing a Single-Drive MZM-Based Optical Carrier Suppression Without Precoding
TL;DR: In this paper, a simple photonic vector signal generation scheme at radio frequency bands enabled by a single-drive Mach-Zehnder modulator-based optical carrier suppression without precoding techniques and optical filter was investigated.
Proceedings ArticleDOI
Mitigation of Multi-user Access Impairments in 5G A-RoF-based Mobile Fronthaul utilizing Machine Learning for an Artificial Neural Network Nonlinear Equalizer
TL;DR: The proposed ANN-NLE is experimentally demonstrated to mitigate intra/inter-band interferences caused by nonlinear impairments in multi-user environments.
Proceedings ArticleDOI
Transmission of microwave-photonics generated 16Gbit/s super broadband OFDM signals in radio-over-fiber system
TL;DR: A super broadband radio-over-fiber system with a record bandwidth of 16 Gbit/s OFDM signals transmitting over both 20 km SMF-28 and wireless air distance of over 6m is designed and experimentally demonstrated.
