Resumo: This dissertation proposes a way to improve the spectral efficiency of generalized frequency division multiplexing (GFDM) through the principles of faster than Nyquist (FTN) signaling, without error rate penalties. This is obtained by undersampling the time-frequency grid, introducing controlled interference to the system. At the receiver, a detection scheme based on the sphere decoder (SD) algorithm is proposed, and its performance is evaluated in terms of bit error rate (BER) under different channel models. The proposed SD has a computational complexity smaller than the maximum likelihood (ML), without presenting significant BER performance loss, even in high interference scenarios, proving that the FTN-GFDM scheme is able to achieve high spectral efficiency in the channels analyzed.

Disserta????o( Mestrado em Engenharia de Telecomunica????es) - Instituto Nacional de Telecomunica????es, [Santa Rita do Sapucai] .https://tede.inatel.br:8080/tede/handle/tede/195This dissertation proposes a way to improve the spectral efficiency of generalized frequency division multiplexing (GFDM) through the principles of faster than Nyquist (FTN) signaling, without error rate penalties.

Isto ?? obtido subamostrando a grade de tempo-frequ??ncia, introduzindo assim uma interfer??ncia controlada no sistema. Este trabalho apresenta um esquema de detec????o baseado no algoritmo sphere decoder (SD) para o receptor e seu desempenho ?? avaliado em termos de taxa de erro de bit (BER) sob diferentes modelos de canal. O SD proposto possui uma complexidade computacional menor que o maximum likelihood (ML), sem perdas significativas de desempenho, mesmo em cen??rios de alta interfer??ncia, provando que o esquema FTN-GFDM ?? capaz de alcan??ar alta efici??ncia espectral considerando os diferentes canais analisados.Submitted by Tede Dspace (tede@inatel.br) on 2019-11-26T15:25:53Z No. of bitstreams: 2 license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5) Disserta????o V.Final Mariana Baracat de Mello.pdf: 5809578 bytes, checksum: c9943e9e0ebf85afe5f77735da3fb4cd (MD5)Made available in DSpace on 2019-11-26T15:25:53Z (GMT).
