In this paper, we present a sound field interpolation for array signal processing (ASP) that is
robust to rotation of a circular microphone array (CMA), and we evaluate beamforming as …

A multichannel speech enhancement system usually consists of spatial filters such as
adaptive beamformers followed by postfilters, which suppress remaining noise. Accurate …

The immense degree of freedom (DOF), high array aperture, non-uniform linear arrays, and
reduced mutual coupling have developed interest in the estimations of the direction of arrival …

As communication technologies advance, millimeter wave (mmWave) signals have been
widely used, leading to the rise of massive multiple input multiple output (MIMO) systems …

Speech processing algorithms often rely on statistical knowledge of the underlying process.
Despite many years of research, however, the debate on the most appropriate statistical …

Signal-dependent beamformers are advantageous over signal-independent beamformers
when the acoustic scenario-be it real-world or simulated-is straightforward in terms of the …

Existing idler fault diagnosis methods have problems in failing to fully obtain global context
information and providing poor diagnostic accuracy. To address these problems, this paper …

Segregating the multiple users in different angular orientations enables to exploit the space
and antenna diversity, thus multiple users can be accommodated in the same frame of time …

In response to the echo and noise interference problems faced by multi-user full-duplex
voice communication scenarios, this work proposes a complete solution from signal …

The covariance matrix, employed for measuring the linear correlation between variables,
plays a vital role in data analysis, such as statistical prediction and hypothesis testing. When …
