Parameters Selection for Filter Bank Precoded Filter Bank Multicarrier Systems

Filter Bank MultiCarrier - Offset QAM (FBMC-OQAM) is now a recognized alternative to Orthogonal Frequency Division Multiplexing (OFDM) for the transmission of multicarrier signals thanks to its improved spectral occupation. However FBMC-OQAM presents a high occurrence of power peaks. In order to reduce the occurrence of large power peaks, we present two efficient precoding methods: Filter Bank (FB) precoding and FB precoding with excess band. We propose the best choice of parameters for these methods in order to optimize performances in terms of peak power reduction, excess band, latency and overhead.
