- W2919579250 abstract "5G paves the way to service-centric adaptation radio link. The transmitted signal is now configured according to the service it provides and the propagation impairments it suffers from. However, in 5G the multi-service multiplexing leads to a poor bandwidth use. Indeed, CP-OFDM is responsible for large out-of-band emission and therefore large guard bands are required between bands of different numerologies. In this paper, the authors investigate the use of filter-bank based waveforms as an alternative of legacy CP-OFDM. Such waveforms prove to be an enabling technology for an efficient multi-service multiplexing. Moreover, it is possible to configure a unique filtering stage, i.e. the PolyPhase-Network, to simultaneously address different numerologies in the same system bandwidth. This result would ease the support of real-time numerology adaptation as one base station could provide different services in the same cell. This paper is rather dedicated on the study of BF-OFDM which is a filter-bank based waveform which relies on a 5G NR OFDM receiver. Nonetheless the waveform provides great results on the considered evaluation scenarios for a reasonable complexity increase." @default.
