—The signal subspace approach for speech enhancement is extended to colored-noise processes. Explicit forms for the linear time-domain-and spectral-domain-constrained estimators are presented. These estimators minimize the average signal distortion power for given constraints on the residual noise power in the time and spectral domains, respectively.(More)
We present a computationally-efficient matrix-vector expression for the solution of a matrix linear least squares problem that arises in multistatic antenna array processing. Our derivation relies on an explicit new relation between Kronecker, Khatri-Rao and Schur-Hadamard matrix products, which involves a selection matrix (i.e., a subset of the columns of(More)
Invited Paper This article reviews analytical results and practical experience with randomized modulation in power electronic converters. After providing a brief overview of power electronics and of relevant switching patterns, we present performance specifications for converters (in terms of electromagnetic interference, vibrations and acoustic noise), and(More)
