Orthogonal Frequency Division Multiplexing (OFDM) technique has its own dominant effect on broadband transmission systems. It has been an excellent waveform choice for next generation wireless communication system such as LTE/LTE-A system. However, the frequency spectrum behavior of subcarrier signals in OFDM is not good enough, which is the main source of problems for future development as the spectrum allotted is limited. Filter Bank Multi-Carrier (FBMC) technique, on the other hand, as a candidate waveform for 5G mobile communications, is an elegant method that solves most of these problems by pulse shaping the individual subcarrier by using a filter bank. This paper, investigates the PHYDYAS prototype filter response for both OFDM and FBMC systems.
