One-Bit Spectrum Sensing for Cognitive Radio
Pei-Wen Wu, Lei Huang, David Ramírez +2
Spectrum sensing in cognitive radio necessitates effective monitoring of wide bandwidths, which requires high-rate sampling. Traditional spectrum sensing methods employing high-pre…
Robust time-of-arrival localization via ADMM
Wenxin Xiong, Christian Schindelhauer, Hing Cheung So
This article considers the problem of source localization (SL) using possibly unreliable time-of-arrival (TOA) based range measurements. Adopting the strategy of statistical robust…
One-Bit Covariance Reconstruction with Non-zero Thresholds: Algorithm and Performance Analysis
Yu-Hang Xiao, Lei Huang, David Ramírez +2
Covariance matrix reconstruction is a topic of great significance in the field of one-bit signal processing and has numerous practical applications. Despite its importance, the con…
Globally Optimized TDOA High Frequency Source Localization Based on Quasi-Parabolic Ionosphere Modeling and Collaborative Gradient Projection
Wenxin Xiong, Christian Schindelhauer, Hing Cheung So
We investigate the problem of high frequency (HF) source localization using the time-difference-of-arrival (TDOA) observations of ionosphere-refracted radio rays based on quasi-par…
Disproving Sum-Difference Co-Array Property
Jisheng Dai, Hing Cheung So
The recently published paper by Gupta and Agrawal [1] exploited the sum-difference co-array (SDCA) to enhance the virtual aperture of sparse arrays. We argue that the key SDCA prop…
