We consider a multi-task wireless sensor network (WSN) where some of the nodes aim at
applying a multi-channel Wiener filter to denoise their local sensor signals, whereas others …

Many multi-microphone speech enhancement algorithms require the relative transfer
function (RTF) vector of the desired speech source, relating the acoustic transfer functions of …

In recent years, signal processing with ad hoc microphone arrays has attracted a lot of
attention. Speech enhancement in noisy, interfered, and reverberant environments is one of …

As the number of connected devices equipped with multiple microphones increases,
scientific interest in distributed microphone array processing grows. Current beamforming …

经过数十年的发展, 麦克风阵列技术日益成熟, 并广泛应用于视频会议, 智能电视,
移动通话和助听器等人机交互系统. 然而, 现实噪声或远距离交互场景中, 限定阵型结构的传统 …

This paper is concerned with online algorithms for the generalized Hermitian eigenvalue
problem (GHEP). We first present an algorithm based on randomization, termed alternate …

This paper deals with the problem of automatic diagonal loading for the linear constrained
minimum power beamformer. To find the beamformer's weights, the linear constrained …

Distortionless speech extraction in a reverberant environment can be achieved by applying
a beamforming algorithm, provided that the relative transfer functions (RTFs) of the sources …

In voice-based human-computer interaction, various environmental noise may interfere with
the normal transmission of information. Noises may typically lead to performance …

This thesis addresses the problem of detection of an unknown binary event. In particular, we
consider centralized detection, distributed detection, and network security in wireless sensor …
