Superfast Line Spectral Estimation
Thomas Lundgaard Hansen, Bernard Henri Fleury, Bhaskar D. Rao
A number of recent works have proposed to solve the line spectral estimation problem by applying off-the-grid extensions of sparse estimation techniques. These methods are preferab…
Relevance Subject Machine: A Novel Person Re-identification Framework
Igor Fedorov, Ritwik Giri, Bhaskar D. Rao +1
We propose a novel method called the Relevance Subject Machine (RSM) to solve the person re-identification (re-id) problem. RSM falls under the category of Bayesian sparse recovery…
A GAMP Based Low Complexity Sparse Bayesian Learning Algorithm
Maher Al-Shoukairi, Philip Schniter, Bhaskar D. Rao
In this paper, we present an algorithm for the sparse signal recovery problem that incorporates damped Gaussian generalized approximate message passing (GGAMP) into Expectation-Max…
Performance of Cell-Free Massive MIMO Systems with MMSE and LSFD Receivers
Elina Nayebi, Alexei Ashikhmin, Thomas L. Marzetta +1
Cell-Free Massive MIMO comprises a large number of distributed single-antenna access points (APs) serving a much smaller number of users. There is no partitioning into cells and ea…
