Identification of Linear Time-Varying Systems Through Waveform Diversity
Andrew Harms, Waheed U. Bajwa, Robert Calderbank
Linear, time-varying (LTV) systems composed of time shifts, frequency shifts, and complex amplitude scalings are operators that act on continuous finite-energy waveforms. This pape…

Finding Zeros: Greedy Detection of Holes
Juhwan Yoo, Yao Xie, Andrew Harms +2
In this paper, motivated by the setting of white-space detection [1], we present theoretical and empirical results for detection of the zero-support E of x \in Cp (xi = 0 for i \in…

A Constrained Random Demodulator for Sub-Nyquist Sampling
Andrew Harms, Waheed U. Bajwa, Robert Calderbank
This paper presents a significant modification to the Random Demodulator (RD) of Tropp et al. for sub-Nyquist sampling of frequency-sparse signals. The modification, termed constra…
