Abstract :
The paper presents analysis of a digital ultra-wideband (UWB) radio receiver operating in the 3.1 GHz to 10.6 GHz band. Analog-to-digital converter (ADC) bit precision is analyzed on two types of UWB signals - OFDM UWB and pulsed UWB - all in the presence of additive white Gaussian noise (AWGN) and a narrowband interferer in the channel. The paper shows how probability of error and the bit resolution of the ADC can be scaled depending on the signal-to-noise ratio (SNR), signal-to-interference ratio (SIR), and the type of UWB signal. It also includes considerations on timing recovery for pulsed UWB.
