Estimation of Sparse MIMO Channels with Common Support
Yann Barbotin, Ali Hormati, Sundeep Rangan +1
We consider the problem of estimating sparse communication channels in the MIMO context. In small to medium bandwidth communications, as in the current standards for OFDM and CDMA…
Group Testing with Probabilistic Tests: Theory, Design and Application
Mahdi Cheraghchi, Ali Hormati, Amin Karbasi +1
Identification of defective members of large populations has been widely studied in the statistics community under the name of group testing. It involves grouping subsets of items…
An Estimation Theoretic Approach for Sparsity Pattern Recovery in the Noisy Setting
Ali Hormati, Amin Karbasi, Soheil Mohajer +1
Compressed sensing deals with the reconstruction of sparse signals using a small number of linear measurements. One of the main challenges in compressed sensing is to find the supp…
Compressed Sensing with Probabilistic Measurements: A Group Testing Solution
Mahdi Cheraghchi, Ali Hormati, Amin Karbasi +1
Detection of defective members of large populations has been widely studied in the statistics community under the name "group testing", a problem which dates back to World War II w…
