Spectrally efficient fronthaul architectures for a cost-effective 5G C-RAN

Abstract [en]

In 5G wireless systems, centralized RAN (C-RAN) is an architectural choice where the signal waveforms received by Remote Radio Heads (RRH) are transparently forwarded to base band units (BBU), in many cases using an optical fronthaul. Although C-RAN highly simplifies the RRH, which is positive from the operational cost standpoint, much of the system complexity and cost is shifted towards the optical fronthaul. In this paper we show how a cost-effective C-RAN requires a spectrally-efficient optical fronthaul, and discuss the technological options to realize it.
