A Review on FBMC: An Efficient Multicarrier Modulation System

Abstract

Multicarrier modulations attract a lot of attention among engineers and researchers working in the field of telecommunications. One specific form of multicarrier modulation referred to as OFDM has been the dominant technology for broadband multicarrier communications. Despite their many advantages, OFDM systems have a few, but important drawbacks. Filter bank multicarrier (FBMC) is an evolution with many advantages over the widespread OFDM multicarrier scheme. Filter banks are an evolved form of subband processing based on Fast Fourier Transforms and addressing some of its shortcomings, at the price of a somewhat increased implementation complexity. In this paper, a review of FBMC and its concept is presented, emphasizing its benefits over OFDM in applications such as Cognitive Radio(CR), Multiple access networks, TVWS, PLC and MIMO communication .
