Filter-bank OFDM transceivers for 5G and beyond
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.
