Dimensioning the physical layer of DSP-based radio waveforms aggregation for Fronthauling

Abstract:

One of the transmission solutions for nextgeneration fronthauling is a "native" radio over fiber transport of a large number of radio waveforms assisted by Digital Signal processing aggregation at the transceiver sides. This solution originally proposed by Huawei and now part of the ITU-T G.sup55 Recommendation has been experimentally demonstrated in some specific system scenario, but we believe system margin for the radio link has not been properly considered. The goal of this paper is providing a more extensive set of theoretical requirements and accordingly give some preliminary experimental results.
