Testing for impropriety of multivariate complex random processes

ICASSP 2016accepted

We consider the problem of testing whether a complex-valued vector random sequence is proper. Past work on this problem is limited to a sequence of independent Gaussian random vectors whereas we allow an arbitrary stationary vector sequence that can be non-Gaussian. A binary hypothesis testing appro…

Quantized matrix completion for low rank matrices

Sonia A. Bhaskar

ICASSP 2015accepted

In this paper, we consider the recovery of a low rank matrix M given a subset of noisy quantized (or ordinal) measurements. We consider a constrained maximum likelihood estimation of M, under a constraint on the entry-wise infinity-norm of M and an exact rank constraint. We provide an upper bound on…
