  Abstract

A variety of multi-carrier schemes called new-waveforms have been studied in order to compensate for the weakness of CP-OFDM such as poor spectral localization, etc. Due to its spectral efficiency and well-localized spectrum, a QAM-FBMC is considered as one of the candidates for 5G mobile communications. In this paper, we describe the criterion for the conventional prototype filters for QAM-FBMC which decide the localization properties and performance, and we suggest a new design criterion for the prototype filters that can be used in practical systems. Also, by using the designed filters, we propose an interference mitigating receiver which is able to cancel the internal interference from filters without a complex signal processing. Lastly, simulation results show the improvement in the performance of the designed filters compared with the conventional filters of QAM-FBMC systems.
