Abstract

This paper compares the performances of filter bank multicarrier (FBMC) and orthogonal frequency division multiplexing (OFDM) under multipath fading channels, in terms of their theoretical system capacities. OFDM generates high levels of out-of-band (OOB) radiation while being resistant to inter-symbol interference (ISI). In contrast, the effect of subcarrier-wise filtering in FBMC inhibits the generation of OOB radiation, which also reduces its adjacent channel interference (ACI). However, it suffers from ISI and inter-carrier interference (ICI), caused by multipath fading. The primary aim of this study is to demonstrate the theoretical system capacity of FBMC and OFDM systems, consider their ACI and multipath fading in an asynchronous scenario, and ascertain the superiority of each approach based on the parameters of guard band and delay spread.
