Experimental Performance Evaluation Of A 5g Spectrum Sharing Scenario Based On Field-Measured Channels

In this paper, an experimental performance evaluation is carried out within a communication scenario that features two of the key enablers of 56: (i) the use of post-OFDIVI modulations and (ii) an efficient use of the spectrum via spectrum sharing. The experimental lab set-up has been assembled so as to operate in conditions as realistic as possible via the actual real-time implementation of the involved transceivers and also via the utilization of propagation channels which have been recorded in a field measurement campaign and which are loaded in a channel emulator that also operates in real-time. The experimental results show that co-existence in a shared spectrum scenario is possible and that the performance degradation is kept at a low level as long as one of the two users is making use of spectrally agile post-OFDM modulations such as filterbank multicarrier (FBMC).
