Pearson-Matthews correlation coefficients for binary and multinary classification and hypothesis testing
Petre Stoica, Prabhu Babu
The Pearson-Matthews correlation coefficient (usually abbreviated MCC) is considered to be one of the most useful metrics for the performance of a binary classification or hypothes…
The Cramer-Rao Bound for Signal Parameter Estimation from Quantized Data
Petre Stoica, Xiaolei Shang, Yuanbo Cheng
Several current ultra-wide band applications, such as millimeter wave radar and communication systems, require high sampling rates and therefore expensive and energy-hungry analogt…
Learning Sparse Graphs via Majorization-Minimization for Smooth Node Signals
Ghania Fatima, Aakash Arora, Prabhu Babu +1
In this letter, we propose an algorithm for learning a sparse weighted graph by estimating its adjacency matrix under the assumption that the observed signals vary smoothly over th…
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…
Polyphase Waveform Design for MIMO Radar Space Time Adaptive Processing
Bo Tang, Jonathan Tuck, Peter Stoica
We consider the design of polyphase waveforms for ground moving target detection with airborne multiple-input-multiple-output (MIMO) radar. Due to the constant-modulus and finite-a…
Robust Prediction when Features are Missing
Xiuming Liu, Dave Zachariah, Petre Stoica
Predictors are learned using past training data which may contain features that are unavailable at the time of prediction. We develop an approach that is robust against outlying mi…
Max-Min Fairness Design for MIMO Interference Channels: a Minorization-Maximization Approach
Mohammad Mahdi Naghsh, Maryam Masjedi, Arman Adibi +1
We address the problem of linear precoder (beamformer) design in a multiple-input multiple-output interference channel (MIMO-IC). The aim is to design the transmit covariance matri…
