An Optimal Channel Estimation Scheme for Intelligent Reflecting Surfaces based on a Minimum Variance Unbiased Estimator
Tobias Lindstrøm Jensen, Elisabeth De Carvalho
In a wireless system with Intelligent Reflective Surfaces (IRS) containing many passive elements, we consider the problem of channel estimation. All the links from the transmitter…
A Fast Interior Point Method for Atomic Norm Soft Thresholding
Thomas Lundgaard Hansen, Tobias Lindstrøm Jensen
The atomic norm provides a generalization of the -norm to continuous parameter spaces. When applied as a sparse regularizer for line spectral estimation the solution can be…
Proceedings of the third "international Traveling Workshop on Interactions between Sparse models and Technology" (iTWIST'16)
V. Abrol, O. Absil, P. -A. Absil +58
The third edition of the "international - Traveling Workshop on Interactions between Sparse models and Technology" (iTWIST) took place in Aalborg, the 4th largest city in Denmark s…
Compressive Sensing for Spread Spectrum Receivers
Karsten Fyhn, Tobias Lindstrøm Jensen, Torben Larsen +1
With the advent of ubiquitous computing there are two design parameters of wireless communication devices that become very important power: efficiency and production cost. Compress…
Accelerated gradient methods for total-variation-based CT image reconstruction
Jakob Heide Jørgensen, Tobias Lindstrøm Jensen, Per Christian Hansen +3
Total-variation (TV)-based Computed Tomography (CT) image reconstruction has shown experimentally to be capable of producing accurate reconstructions from sparse-view data. In part…
Implementation of an Optimal First-Order Method for Strongly Convex Total Variation Regularization
Tobias Lindstrøm Jensen, Jakob Heide Jørgensen, Per Christian Hansen +1
We present a practical implementation of an optimal first-order method, due to Nesterov, for large-scale total variation regularization in tomographic reconstruction, image deblurr…
