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

One of the transmission solutions for nex tgeneration 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

Optimization of DSP-based channel aggregation parameters for front-hauling over PON infrastructure

In this paper we demonstrate the transmission of LTE channels with the DSP-based channel aggregation, for front-hauling applications, over at least a class N1 PON, ranging from EVM=4% for 24 channels up to EVM=8% for 96 channels

Experimental Optimization of DSP-Aggregated Front-hauling Transmission for up to 4x96 LTE radio waveforms

In this paper we demonstrate the transmission of up to 384 LTE channels with the DSP-based channel aggregation, for front-hauling applications, over a conventional PON infrastructure. An analysis on the impact of the optical link on the EVM is shown
