Low-Latency High-Efficiency Mobile Fronthaul With TDM-PON (Mobile-PON)
Journal of Optical Communications and Networking, 2017To meet the capacity requirements of the exponential increase in mobile traffic and to continue to drive down the per-bit cost for mobile service providers, the cloud radio access network (C-RAN) has become a crucial step toward 5G. However, the current C-RAN architecture has some major drawbacks in terms of scalability, cost, and efficiency.

Linearization of a Radio-over-Fiber mobile fronthaul with feedback loop
2017 26th Wireless and Optical Communication Conference (WOCC), 2017The main disadvantage of Radio over Fiber (RoF) links digital predistortion (DPD) is that it is necessary to feedback the output signals at the Remote Radio Head (RRH) in a real scenario. Along the literature digital predistortion on RoF mobile fronthaul architectures considers an ideal feedback system, so it cannot be deployed in real systems.

A Novel DBA Scheme for TDM-PON based Mobile Fronthaul
Optical Fiber Communication Conference, 2014We propose a mobile-DBA with low-latency for a TDM-PON based mobile fronthaul. It utilizes mobile-scheduling information and reduces the latency to about 1/20 of conventional one. Measured latencies (< 50 µs) are enough for LTE.

Wavelength Resource Sharing in Bidirectional Optical Mobile Fronthaul
Journal of Lightwave Technology, 2015In this paper, we propose high-capacity spectrally-efficient optical mobile fronthaul (MFH) architectures featuring wavelength resource sharing, where multiple cell sites share one dense wavelength division multiplexing (DWDM) channel instead of occupying a number of separated DWDM channels.
