In this paper, we study the performance of filter bank multi-carrier (FBMC) transmission systems over doubly-dispersive channels. FBMC generalizes traditional orthogonal frequency-division multiplexing (OFDM) schemes, allowing a non-rectangular sub-channel pulse shape in the time domain. This approach leads to a better spectral containment that improves interference mitigation in several time-variant environments. A general analysis describes the transmultiplexer structure and the time-variant multipath channel model. We specify rectangular filters and short perfect reconstruction (PR) filters that give rise to two families of FBMC transceivers. A performance comparison between these schemes is performed in terms of bit-error-rate using a single-tap per sub-channel equalizer. This study emphasizes the low complexity of the FBMC transceivers in the case of short filters and discusses its usefulness through simulation results in two mobility scenarios.
