Analyzing Weighted Minimization for Sparse Recovery with Nonuniform Sparse Models\footnote{The results of this paper were presented in part at the International Symposium on Information Theory, ISIT 2009}
M. Amin Khajehnejad, Weiyu Xu, A. Salman Avestimehr +1
In this paper we introduce a nonuniform sparsity model and analyze the performance of an optimized weighted minimization over that sparsity model. In particular, we focus…
Improved Sparse Recovery Thresholds with Two-Step Reweighted Minimization
M. Amin Khajehnejad, Weiyu Xu, Salman Avestimehr +1
It is well known that minimization can be used to recover sufficiently sparse unknown signals from compressed linear measurements. In fact, exact thresholds on the sparsit…
Divide-and-conquer: Approaching the capacity of the two-pair bidirectional Gaussian relay network
Aydin Sezgin, A. Salman Avestimehr, M. Amin Khajehnejad +1
The capacity region of multi-pair bidirectional relay networks, in which a relay node facilitates the communication between multiple pairs of users, is studied. This problem is fir…
