Superdirective beamforming has attracted a significant amount of research interest in speech and audio applications, since it can maximize the directivity factor (DF) given an …
In this paper, we consider the problem of parameter estimation of autoregressive (AR) signals from observations corrupted with colored AR (1) noise. The proposed method is …
In this letter we present discrete Fourier transform (DFT) domain minimum mean-squared error (MMSE) estimators for multichannel noise reduction. The estimators are derived …
