Quantization via Empirical Divergence Maximization
Michael A. Lexa
Empirical divergence maximization (EDM) refers to a recently proposed strategy for estimating f-divergences and likelihood ratio functions. This paper extends the idea to empirical…

Compressive and Noncompressive Power Spectral Density Estimation from Periodic Nonuniform Samples
Michael A. Lexa, Mike E. Davies, John S. Thompson
This paper presents a novel power spectral density estimation technique for band-limited, wide-sense stationary signals from sub-Nyquist sampled data. The technique employs multi-c…

Reconciling Compressive Sampling Systems for Spectrally-sparse Continuous-time Signals
Michael A. Lexa, Mike E. Davies, John S. Thompson
The Random Demodulator (RD) and the Modulated Wideband Converter (MWC) are two recently proposed compressed sensing (CS) techniques for the acquisition of continuous-time spectrall…
