The identification of room acoustic impulse responses represents a challenging problem in
the framework of many important applications related to the acoustic environment, like echo …

A wide variety of system identification problems can be efficiently addressed based on the
Kronecker product decomposition of the impulse response, together with low-rank …

Adaptive beamformers use data from sensor arrays to capture signal from a desired
direction without any distortion, in the presence of interfering signals from other directions in …

Sparse Bayesian learning (SBL) exploits sparse information from a Bayesian perspective by
making sparse prior assumptions about the signal. It has good flexibility in modeling sparse …

The identification of long-length impulse responses represents a challenge in the context of
many applications, like echo cancellation. Recently, the problem has been addressed in the …

In this paper, we address the problem of constant-beamwidth beamforming using
nonuniform planar arrays. We propose two techniques for designing planar beamformers …

Recently, the augmented complex-valued normalized subband adaptive filtering (ACNSAF)
algorithm has been proposed to process colored non-circular signals. However, its …

In recent years, active noise control (ANC) systems have attracted a lot of attention since
