Abstract

Filter bank multicarrier (FBMC) is one of the proposed physical layers for 5G, which promises to enable future technologies like cognitive radio, robotic automation, virtual reality etc. This paper highlights how FBMC outperforms orthogonal frequency division multiplexing (OFDM) in various aspects such as data rate, spectral efficiency etc. Moreover, it provides a detailed mathematical analysis of polyphase decomposition of filter banks in FBMC and throws light on significance of offset quadrature amplitude modulation (OQAM) in dealing with channel impairments. The significance of massive MIMO systems along with the suitability of FBMC in its application has also been addressed.
