Learning Pareto-Efficient Decisions with Confidence
Sofia Ek, Dave Zachariah, Petre Stoica
The paper considers the problem of multi-objective decision support when outcomes are uncertain. We extend the concept of Pareto-efficient decisions to take into account the uncert…
Robust Learning in Heterogeneous Contexts
Muhammad Osama, Dave Zachariah, Petre Stoica
We consider the problem of learning from training data obtained in different contexts, where the underlying context distribution is unknown and is estimated empirically. We develop…
Weighted SPICE Algorithms for Range-Doppler Imaging Using One-Bit Automotive Radar
Xiaolei Shang, Jian Li, Petre Stoica
We consider the problem of range-Doppler imaging using one-bit automotive LFMCW1 or PMCW radar that utilizes one-bit ADC sampling with time-varying thresholds at the receiver. The…
RFI Mitigation for One-bit UWB Radar Systems
Tianyi Zhang, Jiaying Ren, Jian Li +2
Radio frequency interference (RFI) mitigation is critical to the proper operation of ultra-wideband (UWB) radar systems since RFI can severely degrade the radar imaging capability…
Sinusoidal Parameter Estimation from Signed Measurements via Majorization-Minimization Based RELAX
Jiaying Ren, Tianyi Zhang, Jian Li +1
We consider the problem of sinusoidal parameter estimation using signed observations obtained via one-bit sampling with fixed as well as time-varying thresholds. In a previous pape…
Joint RFI Mitigation and Radar Echo Recovery for One-Bit UWB Radar
Tianyi Zhang, Jiaying Ren, Jian Li +2
Radio frequency interference (RFI) mitigation and radar echo recovery are critically important for the proper functioning of ultra-wideband (UWB) radar systems using one-bit sampli…
