ABSTRACT:
This invention generally relates to wired and wireless ultra wideband (UWB) data communications apparatus and methods, and in particular to UWB receiver systems and architectures.An ultra wideband (UWB) receiver system comprising: a receiver front end to receive a UWB signal; an analogue-to-digital converter coupled to said receiver front end to digitize said received UBW signal; and a correlator coupled to said analogue-to-digital converter to correlate said digitized UWB signal with a reference signal.
