Abstract— Ultra Wide Band (UWB) wireless systems basedon impulse radio have the potential to provide very highdata rates over short distances. One of the solutions for theUWB communication systems is the Multi Band On-OffKeying (MB-OOK) which consists in an OOK modulationgeneralized over multiple frequency sub-bands andassociated with a demodulation based on a non-trivialenergy threshold comparison. This article presents theanalysis and simulations of an UWB MB-OOK transceiverin the 6-8.5GHz band. This study is focused on the bandpassfilter bank in the transceiver’s architecture. The use ofa Bulk Acoustic Wave (BAW) filter bank in the transceiveris considered. Finally, system performance is estimated forthe proposed architecture.

Index Terms— UWB, MB-OOK, high data rates, BAWfilters
