Blind Compensation of Memoryless Nonlinear Distortions in Sparse Signals
This paper focuses on blind compensation of memoryless nonlinear distortions in sparse signals. A nonlinear distortion tends to decrease the sparsity. We propose, such that the compensated signal is as sparse as po...

On the Limitation of Convex Optimization for Sparse Signal Segmentation
We show that convex optimization methods have fundamental properties that complicate performing signal segmentation based on sparsity assumptions. We review the recently introduced overcomplete sparse segmentation model, we perform ...
