Bits Through Bufferless Queues
Mehrnaz Tavan, Roy D. Yates, Waheed U. Bajwa
This paper investigates the capacity of a channel in which information is conveyed by the timing of consecutive packets passing through a queue with independent and identically dis…
Conditioning of Random Block Subdictionaries with Applications to Block-Sparse Recovery and Regression
Waheed U. Bajwa, Marco F. Duarte, Robert Calderbank
The linear model, in which a set of observations is assumed to be given by a linear combination of columns of a matrix, has long been the mainstay of the statistics and signal proc…
Target Estimation in Colocated MIMO Radar via Matrix Completion
Shunqiao Sun, Athina P. Petropulu, Waheed U. Bajwa
We consider a colocated MIMO radar scenario, in which the receive antennas forward their measurements to a fusion center. Based on the received data, the fusion center formulates a…
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…
