UWB RECEIVER SYSTEM WITH RF ANALOG TO DIGITAL CONVERSION (ADC) BEFORE THE CORRELATION

摘要

The disclosure 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 (504) to receive a UWB signal; an analogue-to-digital converter (508) coupled to said receiver front end to digitise said received UWB signal; and a correlator (514) coupled to said analogue-to-digital converter to correlate said digitised UWB signal with a reference signal.
