Successive Concave Sparsity Approximation for Compressed Sensing
Mohammadreza Malek-Mohammadi, Ali Koochakzadeh, Massoud Babaie-Zadeh +2
In this paper, based on a successively accuracy-increasing approximation of the norm, we propose a new algorithm for recovery of sparse vectors from underdetermined measur…

DOA Estimation in Partially Correlated Noise Using Low-Rank/Sparse Matrix Decomposition
Mohammadreza Malek-Mohammadi, Magnus Jansson, Arash Owrang +2
We consider the problem of direction-of-arrival (DOA) estimation in unknown partially correlated noise environments where the noise covariance matrix is sparse. A sparse noise cova…
