ABSTRACT:
Described herein are ultra wideband (UWB) receiver systems, and applications thereof. Such a UWB receiver includes a receiver front end and a correlator coupled to the receiver front end. The receiver front end is configured to receive a UWB signal having a plurality of multipath components. The correlator is configured to correlate the UWB signal with a reference signal. The UWB signal includes a plurality of pulses, wherein each pulse has a plurality of multipath components. The reference signal also includes a plurality of multipath components of the pulse. The correlator includes at least one correlator module configured to correlate a plurality of the multipath components of the pulse with the reference signal.
