A Lower Bound on the Estimator Variance for the Sparse Linear Model

Sebastian Schmutzhard, Alexander Jung, Franz Hlawatsch +2

We study the performance of estimators of a sparse nonrandom vector based on an observation which is linearly transformed and corrupted by additive white Gaussian noise. Using the…
