Abstract

Filter bank multicarrier (FBMC) system is the one of the favorable waveform candidates to satisfy the demands of future cellular and wireless communication networks. FBMC use prototype filters with lower side lobe and faster spectral decay, which enables it to have the advantages of reduced out-of-band energy and theoretically higher spectral efficiency (SE) compared to conventional multicarrier scheme i.e., orthogonal frequency division multiplexing (OFDM). These systems also have the ability to facilitate aggregation of non-adjacent bands to acquire higher bandwidths for data transmission. They also support asynchronous transmissions to reduce signaling overhead to meet the ever increasing demand of high data rate transmission in future wireless networks. In this paper, we discuss the fundamental difference between multicarrier scheme such as FBMC and conventional OFDM system along with a comparison between the two techniques and also evaluated the computational complexity of OFDM and FBMC systems.
