Mobile Fronthaul Architecture and Technologies: a RAN Equipment Assessment [PDF]

Optical Fiber Communication Conference, 2017
Optical fiber is the required technology for Radio Access Network (RAN) backhaul and fronthaul. We report the evolution of RAN equipment including the advent of virtualization and an investigation of the required architecture and optical access technologies.

Fronthaul evolution: From CPRI to Ethernet [PDF]

, 2015
It is proposed that using Ethernet in the fronthaul, between base station baseband unit (BBU) pools and remote radio heads (RRHs), can bring a number of advantages, from use of lower-cost equipment, shared use of infrastructure with fixed access networks,

Wavelength and Bandwidth Allocation for Mobile Fronthaul in TWDM-PON [PDF]

IEEE Transactions on Communications, 2019
Time- and wavelength- division multiplexed passive optical network (TWDM-PON) has attracted considerable attention for the next generation optical access systems. Among potential applications of TWDM-PON, a major application is the support of mobile fronthaul streams between radio units (RUs) and distributed units (DUs) in the centralized radio access ...

Optimal Design of Mobile Fronthaul Delta-Sigma Modulator based on Search Algorithm

Guangtongxin yanjiu, 2022
The Common Public Radio Interface (CPRI) used in mobile fronthaul has low spectrum efficiency. In this paper, we propose to use Delta-Sigma Modulation (DSM) technology as a new fronthaul interface.

Flexible and Efficient DSP-Assisted Subcarrier Multiplexing for an Analog Mobile Fronthaul [PDF]

IEEE Photonics Technology Letters, 2021
The digital formation of an analog subcarrier multiplex employing in combination both a technique using pre-IFFT frequency-domain samples and one using post-IFFT time-domain samples is proposed and demonstrated. This combined technique enables a compromise for sampling rate requirements, while maintaining low complexity and good performance.
