Filterbank-based multicarrier modulations as OFDM with offset QAM (OFDM/OQAM) can provide a time-frequency well-localized pulse shape. We can exploit this property to reduce the intersymbol interference (ISI) and interchannel interference (ICI) when the transmission is over time and frequency dispersive channels. Several criteria can satisfy this goal. In this paper, we introduce a new criterion to optimize the OFDM/OQAM pulse shape. The proposed criterion is flexible and leads to a fast design optimization procedure. In addition the pulse shape obtained is perfectly orthogonal.
