Abstract

We review alternative solutions for optical fronthauling in next generation fixed-mobile converged architectures that try to solve the problems related to the extremely high bit rates required by current fronthauling implementations based on the so-called digitized Radio over Fiber (as for the CPRI or OBSAI standards). In particular, we present our most recent results on Digital Signal Processing (DSP) assisted Frequency Division Multiplexed (FDM) aggregated radio over fiber solutions. We experimentally show two DSP-based optimization at the transmitter and/or receiver that improves the received Error Vector Magnitude (EVM). Moreover, we discuss on simple spectral estimation of the EVM parameter at the Remote Radio Head (RRH).
