High-Resolution Ultrasound Sensing for Robotics Using Dense Microphone Arrays
IEEE Access, 2020 State-of-the-art autonomous vehicles use all kinds of sensors based on light, such as a camera or LIDAR (Laser Imaging Detection And Ranging). These sensors tend to fail when exposed to airborne particles.

A novel adaptive beamforming scheme for array signal data processing
EURASIP Journal on Wireless Communications and Networking, 2023 When the desired signal data exists in the array received data or the steering vector has a mismatch problem, the current traditional adaptive beamformers will suffer from the effect of the desired signal cancelation phenomenon, resulting in a sharp ...

Elementary transformation analysis for Array-OL [PDF]
, 2007 Array-OL is a high-level specification language dedicated to the definition of intensive signal processing applications. Several tools exist for implementing an Array-OL specification as a data parallel program. While Array-OL can be used directly, it is

Transmit Array Interpolation for DOA Estimation via Tensor Decomposition in 2D MIMO Radar
, 2017 In this paper, we propose a two-dimensional (2D) joint transmit array interpolation and beamspace design for planar array mono-static multiple-input-multiple-output (MIMO) radar for direction-of-arrival (DOA) estimation via tensor modeling.

Tensor-based approach to the co-prime planar array signal processing
Tongxin xuebao, 2020 For the co-prime planar array (CPPA) consisting of two sparse uniform rectangular array (URA),a new processing method based on tensor algebra was proposed to enhance the degrees of freedom (DoF).By dividing each URA into some overlapping subarrays,the ...

A new approach to the spatio-temporal pattern identification in neuronal multi-electrode registrations [PDF]
, 2007 A lot of methods were created in last decade for the spatio-temporal analysis of multi-electrode array (MEA) neuronal data sets. All these methods were implemented starting from a channel to channel analysis, with a great computational effort and ...
