Adaptive decision fusion based cooperative spectrum sensing for cognitive radio systems
(IEEE, 2011)In this paper, an online Adaptive Decision Fusion (ADF) framework is proposed for the central spectrum awareness engine of a spectrum sensor network in Cognitive Radio (CR) systems. Online learning approaches are powerful ... -
Deconvolution using projections onto the epigraph set of a convex cost function
(IEEE, 2014)A new deconvolution algorithm based on making orthogonal projections onto the epigraph set of a convex cost function is presented. In this algorithm, the dimension of the minimization problem is lifted by one and sets ... -
Denoising using projections onto the epigraph set of convex cost functions
(IEEE, 2014)A new denoising algorithm based on orthogonal projections onto the epigraph set of a convex cost function is presented. In this algorithm, the dimension of the minimization problem is lifted by one and feasibility sets ... -
Projection-based wavelet denoising [lecture notes]
(Institute of Electrical and Electronics Engineers Inc., 2015)In this lecture note, we describe a wavelet domain denoising method consisting of making orthogonal projections of wavelet (subbands) signals of the noisy signal onto an upside down pyramid-shaped region in a multidimensional ... -
Projections onto convex sets (POCS) based optimization by lifting
(IEEE, 2013)A new optimization technique based on the projections onto convex space (POCS) framework for solving convex and some non-convex optimization problems are presented. The dimension of the minimization problem is lifted by ... -
Projections onto the epigraph set of the filtered variation function based deconvolution algorithm
(IEEE, 2017)A new deconvolution algorithm based on orthogonal projections onto the hyperplanes and the epigraph set of a convex cost function is presented. In this algorithm, the convex sets corresponding to the cost function are ...
