Resumo: Generalized Frequency Division Multiplexing (GFDM) is a waveform, initially proposed for 5G, that can play an important role in some applications. It offers low out-of-band emission, good spectral efficiency and has the flexibility to cover the 5G requirements in remote area scenarios. The GFDM receiver implementation complexity poses restrictions to the use of this powerful waveform in constrained resources devices, such as the ones used in Internet of Things (IoT). This thesis proposes, a sub-optimal receiver chain using frequency-domain equalization, offering a complexity comparable to the Zero-Forcing (ZF) receiver while achieving performance close to the Minimum Mean Square Error (MMSE) receiver. The study also evaluates the proposed equalizer performance under frequency selective fading channel for the SingleInput/Single-Output (SISO) and Multiple-Input/Multiple-Output (MIMO) cases. Simulation results show that with a small increment in complexity, in comparison with ZF, a performance gain in Symbol Error Rate (SER) can be obtained. An implementation of the proposed chain using the Software Defined Radio (SDR) approach, suggests that the proposed scheme is feasible for practical real-time deployments.

Ela oferece baixa emiss??o fora da faixa, boa efici??ncia espectral e oferece flexibilidade para cobrir os requisitos do 5G em cen??rios de ??rea remota. A complexidade de implementa????o do receptor GFDM imp??e restri????es ao uso desta poderosa forma de onda em dispositivos com recursos restritos, como os usados em IoT. Esta tese prop??e uma cadeia de recep????o sub-??tima usando equaliza????o no dom??nio da frequ??ncia, oferecendo uma complexidade compar??vel a do receptor ZF, enquanto se obt??m um desempenho pr??ximo ao do receptor MMSE. O estudo tamb??m avalia o desempenho sistema proposto em canal com desvanecimento seletivo em frequ??ncia para os casos SISO e MIMO. Os resultados das simula????es mostram que, com um pequeno acr??scimo de complexidade, em compara????o com o ZF, e poss??vel obter um ganho de desempenho na SER. Uma implementa????o da cadeia proposta, utilizando a abordagem SDR, sugere que este esquema e vi??vel para implementa????o em sistemas de comunica????o pr??ticos.Submitted by Tede Dspace (tede@inatel.br) on 2021-11-22T20:01:41Z No. of bitstreams: 2 license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5) Low complexity Sub-optimal GFDM Receiver for Remote Areas.pdf: 21514522 bytes, checksum: 744844227b5e4c9df6656709753b23df (MD5)Made available in DSpace on 2021-11-22T20:01:41Z (GMT).
