An empirical eigenvalue-threshold test for sparsity level estimation from compressed measurements
(European Signal Processing Conference, EUSIPCO, 2014)Compressed sensing allows for a significant reduction of the number of measurements when the signal of interest is of a sparse nature. Most computationally efficient algorithms for signal recovery rely on some knowledge ... -
Restricted Neyman-Pearson approach based spectrum sensing in cognitive radio systems
(Bilkent University, 2012)Over the past decade, the demand for wireless technologies has increased enormously, which leads to a perceived scarcity of the frequency spectrum. Meanwhile, static allocation of the frequency spectrum leads to ... -
Stochastic signaling for power constrained communication systems
(Bilkent University, 2011)In this thesis, optimal stochastic signaling problem is studied for power constrained communications systems. In the first part, optimal stochastic signaling problem is investigated for binary communications systems under ...
