Near-Optimal Detection in MIMO Systems using Gibbs Sampling
Morten Hansen, Babak Hassibi, Alexandros G. Dimakis +1
In this paper we study a Markov Chain Monte Carlo (MCMC) Gibbs sampler for solving the integer least-squares problem. In digital communication the problem is equivalent to performi…
Violating the Ingleton Inequality with Finite Groups
Wei Mao, Babak Hassibi
It is well known that there is a one-to-one correspondence between the entropy vector of a collection of n random variables and a certain group-characterizable vector obtained from…
Sparse Recovery of Positive Signals with Minimal Expansion
M. Amin Khajehnejad, Alexandros G. Dimakis, Weiyu Xu +1
We investigate the sparse recovery problem of reconstructing a high-dimensional non-negative sparse vector from lower dimensional linear measurements. While much work has focused o…
Weighted Minimization for Sparse Recovery with Prior Information
M. Amin Khajehnejad, Weiyu Xu, Salman Avestimehr +1
In this paper we study the compressed sensing problem of recovering a sparse signal from a system of underdetermined linear equations when we have prior information about the proba…
