Abstract

Filter Bank Multicarrier (FBMC) is a multitone modulation
technique that is expected to replace the Orthogonal Frequency Division
Multiplexing (OFDM) due to its inherent characteristics that makes it immune
to channel dispersive effect on the transmitted signal in both time and
frequency. The most effective ingredient in the FBMC is the pulse shaping that
the OFDM symbol lacks. In this paper, a comparative study is presented
between different pulse shapes used in the FBMC like the RRC, PHYDIAS,
IOTA and Hermite function alongside the conventional OFDM.
