Avaliação da performance do sistema QAM-FBMC utilizando filtros Gaussianos curtos

The waveform design for 5G mobile communications networks is a challenge due to its asynchronous heterogeneous scenario. Compared to OFDM, higher spectral efficiency and superior spectrum confinement has been taken into consideration for future radio access technologies. Due its characteristics, QAM-FBMC have drawn attention as a candidate. In this work, we have presented the measurement results of some useful parameters of QAM-FBMC systems like BER, OOBE and interference by using different Gaussian filters. The performance evaluation results show the effects of the choosing alpha, and give the necessary tools to select the ideal alpha to achieve the best results.
