Abstract

UWB signals are very suitable for localization, since their high time resolution can provide precise time of arrival (TOA) estimation. However, a major challenge in UWB signal processing is the requirement for high sampling rate. The theory of compressive sensing (CS) makes processing UWB signal at a low sampling rate possible via analog-toinformation converter (AIC) if the signal has a sparse representation in a certain space. In this paper, a new framework called residual analog-to-information converter (RAIC) is proposed to improve AIC performance by adding a signal prediction/cancellation module in front of AIC. The structure of RAIC is designed and analyzed.
