ABSTRACT
Ultra Wide Band (UWB) wireless systems based on impulse radio have the potential to provide very high data rates over short distances. One of the solutions for the UWB communication systems is the Multi Band On-Off Keying (MB-OOK) which consists in an OOK modulation generalized over multiple frequency sub-bands and associated with a demodulation based on a non-trivial energy threshold comparison. This article presents the analysis and simulations of an UWB MB-OOK transceiver in the 6-8.5GHz band. This study is focused on the bandpass filter bank in the transceiver’s architecture. The use of a Bulk Acoustic Wave (BAW) filter bank in the transceiver is considered. Finally, system performance is estimated for the proposed architecture.
