Noisy Signal Recovery via Iterative Reweighted L1-Minimization

In many cases, the solution can be obtained by solving an L1-minimization problem, and this method is accurate even in the presence of noise.

Sparse signal recovery in the presence of colored noise and rank ...

In this work, we address the recovery of sparse and compressible vectors in the presence of colored noise possibly with a rank-deficient noise covariance ...

Recovery of single source signal from noisy and reverberant ...

We mainly focus on the recovery of the source signal and the estimation of the FIR coefficients in the presence of a larger amount of noise by making use of the ...
